我们在这里应该是安全的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We should be safe here 58 00:05:29,358 --> 00:05:33,095 但是金星快车空间探测器却时刻提醒着我们 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But the Venus Express space

我们会被腐蚀、窒息、压碎和烤焦 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Stick around and we'd be corroded suffocated, crushed and baked 65 00:06:16,872 --> 00:06:19,942 任何东西都无法在这里生存 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Nothing can survive here. 66 00:06:21,577 --> 00:06:24,746 即使像前苏联金星号机器人探测器 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Not even this Soviet robotic probe. 67 00:06:24,913 --> 00:06:29,251 它的厚重装甲已被这极端的大气环境给毁了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its heavy armor's been trashed by the extreme atmosphere. 68 00:06:40,562 --> 00:06:45,901 从地球看她是多么可爱 近观这个女神却是可怕的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So lovely from Earth, up close, this goddess is hideous 69 00:06:59,882 --> 00:07:01,884 她是来自地狱的姊妹 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}She's the

{\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}All that carbon dioxide is trapping the Sun's heat. 72 00:07:09,191 --> 00:07:11,026 金星正在燃烧 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Venus is burning up. 73 00:07:11,193 --> 00:07:14,496 这是无节制的全球气候变暖 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's global warming gone wild 74 00:07:14,663 --> 00:07:18,533 在它变暖之前或许是美丽而平静的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Before it took hold, maybe Venus was beautiful, calm... 75 00:07:18,700 --> 00:07:21,703 ...很像她的姊妹星 地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...more like her sister planet, Earth. 76 00:07:21,870 --> 00:07:25,207 也许就它是我们地球的未来 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So this could be Earth's future 77 00:07:27,542 --> 00:07:29,611 那些闪烁的星星哪里去了？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Where are the twinkling stars? 78 00:07:29,778 --> 00:07:33,181 美丽的圆球滑进了太空？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The beautiful spheres gliding through space? 79 00:07:33,348 --> 00:07:37,586 或许我们不应该来这里 我们应该回去 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe we shouldn't be out here, maybe we should turn back 80 00:07:38,453 --> 00:07:42,591 但是太阳有催眠般的魔力 象美杜莎（古希腊神话中3位蛇发女怪之一） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But there's something about the Sun, something hypnotic, like the Medusa 81 00:07:42,758 --> 00:07:46,895 可怕的让人无法正视，也无法抗拒她的力量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Too terrible to look at, too powerful to resist 82 00:07:47,429 --> 00:07:52,467 引诱我们继续前进 像飞蛾扑火 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Luring us onward on, like a moth to a flame. 83 00:07:54,670 --> 00:07:59,608 等等，这里还有其他东西被太阳炙烤 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Wait ,there's something else, obscured by the sun 84 00:08:00,042 --> 00:08:02,344 它一定是水星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It must be Mercury. 85 00:08:03,345 --> 00:08:08,016 太靠近太阳，就会这样 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Get too close to the sun, this is what happens. 86 00:08:08,317 --> 00:08:10,652 这里温度剧烈变化 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Temperatures swing wildly here 87 00:08:10,819 --> 00:08:14,623 晚上会到零下275度（-170°C） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}At night, it's minus 275 degrees 88 00:08:14,790 --> 00:08:18,493 ...正午则超过800度（400°C） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...come midday, it's 800 plus. 89

MESSENGER space probe is telling us something strange. 91 00:08:32,908 --> 00:08:37,746 相对体积来说，小小的水星具有强大的引力 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}For its size, Mercury has a powerful gravitational pull. 92 00:08:39,581 --> 00:08:44,119 它就像一个裹着薄薄岩石层的大铁球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's a huge ball of iron, covered with a thin veneer of rock 93 00:08:44,286 --> 00:08:48,523 这是一颗大行星留下的核心 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The core of what was once a much larger planet. 94 00:08:49,224 --> 00:08:50,792 其他部分去哪里了呢？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So where's the rest of it? 95 00:08:50,959 --> 00:08:54,096 或许是一个迷路的行星猛地撞进了水星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe a stray planet slammed into Mercury 96 00:08:54,262 --> 00:08:59,735 ...在一场致命的宇宙弹球游戏中水星的外层被炸掉了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...blasting away its outer layers in a deadly game of cosmic pinball 97 00:09:02,437 --> 00:09:07,776 这些游荡的行星在宇宙中疯狂地掠过 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Whole worlds on the loose careening wildly across the cosmos... 98 00:09:07,943 --> 00:09:10,379 ...毁掉他们道路上的一切

{\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Everything is telling us to turn back. 102 00:09:19,554 --> 00:09:22,224 但是谁又能抗拒的了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But who could defy this? 103 00:09:22,557 --> 00:09:27,396 散发着迷人光彩的太阳？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Sun in all its mesmerizing splendor 104 00:09:28,830 --> 00:09:32,401 我们的光线，我们的生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our light, our lives... 105 00:09:32,567 --> 00:09:35,604 我们的一切都被太阳控制着 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...everything we do is controlled by the Sun 106 00:09:35,771 --> 00:09:38,140 依赖于它 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Depends on it 107 00:09:38,807 --> 00:09:44,046 它是驾着战车穿越天际的希腊美男子太阳神 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's the Greek god Helios driving his chariot across the sky 108 00:09:44,212 --> 00:09:47,783 是每天重生的埃及神“拉”（埃及神话里的太阳神） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Egyptian god Ra reborn every day 109 00:09:47,949 --> 00:09:51,420 以及巨石阵夏至的日出 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The summer solstice sun rising at Stonehenge. 110 00:09:51,586 --> 00:09:52,954 数百万年来 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}For millions of years... 111 00:09:53,121 --> 00:09:59,261 我们对太阳神的景仰止于远观 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...this was as close as it got to staring into the face of God 112 00:10:07,969 --> 00:10:09,538 由于实在太远 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's so far away... 113 00:10:09,704 --> 00:10:13,942 如果太阳熄灭了，8分钟后我们才会知道 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it is burned out, we wouldn't know about it for eight minutes 114 00:10:17,279 --> 00:10:22,117 太阳大到可以装下100万颗地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's so Big, you could fit one million Earths inside it 115 00:10:35,430 --> 00:10:39,401 谁需要这些数字呢 我们看到了它的真面目 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But who needs number? we've got the real thing 116 00:10:42,737 --> 00:10:47,175 我们每天看到太阳挂在天空的熟悉面孔 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We see it every day, a familiar face in our sky 117 00:10:47,843 --> 00:10:52,714 现在近观它，又陌生起来 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Now, up close, it's unrecognizable. 118 00:10:53,615 --> 00:10:57,853 由炙热气体形成的汹涌大海 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A turbulent sea of incandescent gas 119 00:10:58,653 --> 00:11:02,157 表面温度超过1万度（5000°C） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The thermometer pushes 10,000 degrees 120 00:11:04,759 --> 00:11:10,332 难以置信的是它的核心温度则可以到数千万度 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}can't imagine how hot the core is ,could be tens of millions of degrees 121 00:11:20,408 --> 00:11:23,478 这里热到足以能够 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Hot enough to transform millions of tons of matter 122 00:11:23,645 --> 00:11:27,215 每秒钟把数百万吨物质转化成能量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...into energy every second 123 00:11:27,382 --> 00:11:31,686 超过人类有史以来产生的所有能量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}More than all the energy ever made by mankind 124 00:11:32,220 --> 00:11:36,091 地球上所有的核武器对于它都是小巫见大巫 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Dwarfing the power of all the nuclear weapons on Earth. 125 00:11:36,258 --> 00:11:40,962 在地球，这些能量是我们利用的光和热 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Back home, we use this energy for light and heat 126 00:11:41,730 --> 00:11:46,234 近距离观看时，却是令人感到不安 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But up close, there's nothing comforting about the Sun. 127 00:11:48,170 --> 00:11:54,376 太阳的电磁活动迸发出巨大的炙热气体环状物（日珥） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its electrical and magnetic forces erupt in giant molten gas loops. 128 00:11:54,543 --> 00:11:57,679 有的足有一打地球那么大 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Some are larger than a dozen Earths 129 00:11:58,113 --> 00:12:01,449 释放的能量超过一千万个火山 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}More powerful than 10 million volcanoes. 130 00:12:14,930 --> 00:12:19,834 当它喷发的时候 就会露出下面温度较低的部分 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And when they burst through they expose cooler layers below... 131 00:12:20,835 --> 00:12:23,538 形成太阳黑子 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...making sunspots. 132 00:12:25,407 --> 00:12:29,477 太阳黑子比周围温度低一些 所以看起来是黑的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A fraction cooler than their surrounding, sunspots look black... 133 00:12:29,644 --> 00:12:32,314 但仍比地球任何东西都热 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...But they're hotter than anything on Earth. 134 00:12:32,480 --> 00:12:38,186 太阳黑子同样巨大，超过地球大小的20倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And massive up to 20 times the size of Earth. 135 00:12:52,801 --> 00:12:57,072 但是总有一天，这一切都会结束 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But one day, all this will stop 136 00:12:57,239 --> 00:13:00,075 太阳的燃料会耗尽 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Sun's fuel will be spent. 137 00:13:05,113 --> 00:13:09,184 太阳死去，地球也会随之死亡 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And when it dies, the Earth will follow 138 00:13:12,954 --> 00:13:17,192 这个神祗创造了生命，也会摧毁生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This god creates life, destroys it... 139 00:13:17,359 --> 00:13:20,328 要求我们保持距离 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and demands we keep out distance 140 00:13:28,503 --> 00:13:31,473 这个彗星太靠近太阳了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This comet strayed too close 141 00:13:31,640 --> 00:13:34,576 它被太阳的热量蒸发 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Sun's heat is boiling it away... 142 00:13:34,743 --> 00:13:38,713 产生绵延数百万英里的彗尾 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...creating a tail that stretches for millions of miles. 143 00:13:49,524 --> 00:13:51,660 这里冰冷彻骨 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's freezing in here. 144 00:13:51,826 --> 00:13:57,432 我们清楚彗星来自哪里 它来自深太空的冰冻垃圾 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's no doubt where this comet's from, the icy wastes of deep space 145 00:13:59,534 --> 00:14:03,371 但你看这些蒸汽、间歇泉和尘埃 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But all this steam and geysers and dust... 146 00:14:03,705 --> 00:14:08,476 这是太阳正在融化彗星的冰冻核心 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it's the Sun again, melting the comet's frozen heart. 147 00:14:08,643 --> 00:14:09,944 太奇异了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Strange. 148 00:14:10,111 --> 00:14:15,650 犹如外面包裹着肮脏沥青的巨大脏雪球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A kind of vast, dirty snowball, covered in grimy tar 149 00:14:17,786 --> 00:14:20,255 看起来像是有机物的小颗粒 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Tiny grains of what looks like organic material... 150 00:14:20,422 --> 00:14:24,659 被冷冻保存 谁会知道已经保存了多久 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...preserved on ice, since who knows when... 151 00:14:25,460 --> 00:14:28,496 也许和太阳系同龄 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...maybe even the beginning of the solar system. 152 00:14:30,665 --> 00:14:35,003 如果像这样一颗彗星在数十亿年前撞到年轻的地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Say a comet like this crashed into the young Earth billions of years ago. 153 00:14:35,170 --> 00:14:38,540 也许带来了生命原始物质... {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe it delivered organic material and water 154 00:14:38,707 --> 00:14:40,809 ...有机物和水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the raw ingredients of life 155 00:14:40,975 --> 00:14:43,445 彗星甚至可能在地球上播下生命之种 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It may even have sown the seeds of life on Earth... 156 00:14:43,611 --> 00:14:47,148 后来进化成你和我 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...that evolved into you and me 157 00:14:55,790 --> 00:14:59,361 如果彗星现在撞上地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But say it crashed into the Earth now 158 00:14:59,527 --> 00:15:05,467 想想恐龙吧 被彗星或是小行星的撞击彻底灭绝 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Think of the dinosaurs, wiped out by a comet or asteroid strike 159 00:15:06,968 --> 00:15:09,237 这只是时间问题 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's only a question of time. 160 00:15:09,404 --> 00:15:14,542 毫无疑问，总有一天我们会步恐龙的后尘 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Eventually, one day, we'll go the way of the dinosaurs 161 00:15:21,916 --> 00:15:26,488 如果地球上的生命灭绝了 我们会被困在这里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}If life on Earth was wiped out, we'd be stuck out here... 162 00:15:26,654 --> 00:15:31,059 无家可归，漂泊在危险宇宙中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...homeless, adrift in a hostile universe 163 00:15:31,459 --> 00:15:34,195 我们需要找一个新家 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We'd need to find another home 164 00:15:34,963 --> 00:15:37,966 在几百万甚至数十亿的行星中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Among the millions, billions of planets... 165 00:15:38,133 --> 00:15:43,104 一定会有一个行星不会很热，也不会很冷 有空气、阳光和水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...there must be one that's not too hot, not too cold, with air, sunlight, water... 166 00:15:43,271 --> 00:15:47,275 可以让我们舒适居住,生活 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...where, like Goldilocks, we could comfortably live 167 00:15:51,946 --> 00:15:53,948 红色行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The red planet 168 00:15:54,115 --> 00:15:57,252 我们都熟知的火星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unmistakably Mars. 169 00:15:59,788 --> 00:16:02,624 几个世纪以来，我们一直都在寻找火星上的同伴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}For centuries, we've looked to Mars for company... 170 00:16:02,791 --> 00:16:05,059 寻找生命迹象 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...for signs of life 171 00:16:12,033 --> 00:16:15,904 那里有外星生物吗？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Could there be extraterrestrial life here? 172 00:16:18,306 --> 00:16:22,243 我们准备好改写史书，撕毁科学书籍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Are we ready to rewrite the history books, to tear up the science books... 173 00:16:22,410 --> 00:16:26,381 颠覆我们的世界了吗？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to turn our world upside down? 174 00:16:27,315 --> 00:16:31,853 接下来发生的可能会改变一切 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}What happens next could change everything 175 00:16:40,361 --> 00:16:43,965 火星比任何其他行星都能激发我们的遐想 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Mars is the planet that most captures our imagination. 176 00:16:44,132 --> 00:16:48,002 想到科幻电影、漫画，你会联想到什么- {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Think of B-movies, sci-fi comics, what follows? 177 00:16:48,169 --> 00:16:49,404 火星人？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Martians? 178 00:16:49,571 --> 00:16:52,307 这都是虚构的，对吗？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's all just fiction, right? 179 00:16:54,242 --> 00:16:57,645 但如果这里真的有生物呢？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But what it there really is something here? 180 00:16:58,713 --> 00:17:02,717 无法想象，近观火星是一个死去的行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Hard to imagine, though. Up close, this is a dead planet 181 00:17:03,785 --> 00:17:09,524 使得地球适宜居住的演化过程几亿年前在火星上就停止了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The activity that makes the Earth livable shut down millions of years ago here 182 00:17:09,991 --> 00:17:12,126 红色、死寂 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Red and dead 183 00:17:12,293 --> 00:17:15,230 火星是一块巨大的化石 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Mars is a giant fossil. 184 00:17:19,834 --> 00:17:24,038 等一下，还有东西在活动 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Wait. Something is alive 185 00:17:24,205 --> 00:17:26,441 一个巨大的尘暴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A dust devil, a big one 186 00:17:26,608 --> 00:17:29,310 绝对超过地球上最大的龙卷风 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Bigger than the biggest twisters back home. 187 00:17:29,477 --> 00:17:31,112 这里有风 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's wind here 188 00:17:31,279 --> 00:17:34,249 有风说明有空气 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And where there's wind, there's air 189 00:17:34,749 --> 00:17:39,020 可以维持外星生物的空气 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Could that air sustain extraterrestrial life? 190 00:17:44,626 --> 00:17:47,762 但对我们的呼吸来说，火星的空气太稀薄了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's too thin tor us to breathe. 191 00:17:48,496 --> 00:17:50,698 而且这里没有臭氧层 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And there's no ozone layer 192 00:17:50,865 --> 00:17:55,670 没有什么能够保护其不受太阳紫外线的伤害 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Nothing to protect us against the Sun's ultraviolet rays. 193 00:17:56,871 --> 00:17:58,773 这里有水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There is water... 194 00:17:58,940 --> 00:18:03,211 但在彻骨的严寒中只能永远被冰冻 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...But frigid temperatures keep it in a constant deep freeze 195 00:18:05,246 --> 00:18:08,182 很难相信有什么可以在这里生存 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's hard to believe anything could live here 196 00:18:11,786 --> 00:18:16,791 但是在地球 极冷和极热的地方都有生物存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Back on Earth, there are creatures that survive in extreme cold, heat... 197 00:18:16,958 --> 00:18:19,260 即使在最深的海沟 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...even in the deepest ocean trenches 198 00:18:19,427 --> 00:18:21,896 生命好像病毒 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's as though life is a virus. 199 00:18:22,063 --> 00:18:25,667 会适应环境、会散播 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It adapts, spreads 200 00:18:25,833 --> 00:18:28,269 也许我们现在正在携带着 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe that's what we're doing right now... 201 00:18:28,436 --> 00:18:33,575 生命的病毒穿越宇宙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...carrying the virus of life across the universe. 202 00:18:36,978 --> 00:18:41,916 即使在最极端的环境里，生命都会找到生存的办法 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Even in the most extreme conditions life usually finds a way. 203 00:18:42,083 --> 00:18:43,918 但在这个死去的行星上 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But on a dead planet? 204 00:18:44,085 --> 00:18:49,924 没有活动去补充它土壤中的成分 没有热量使其冰冻水融化 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}With no way to replenish its soil, no heat to melt its frozen water? 205 00:18:56,230 --> 00:19:00,501 还有大量尘埃，让我们无法辨别方位 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}All this dust, it's hard to see where we're going 206 00:19:08,276 --> 00:19:13,414 奥林匹斯山，以希腊众神的家乡命名 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Olympus Mons, named after the home of the Greek gods 207 00:19:13,581 --> 00:19:16,150 一座巨大的古火山 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A vast ancient volcano. 208 00:19:16,317 --> 00:19:18,953 超过珠穆朗玛峰的三倍高。 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Three times higher than Everest. 209 00:19:19,787 --> 00:19:22,790 没有活动的迹象 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's no sign of activity. 210 00:19:24,058 --> 00:19:29,430 自1970年代发现它时就宣告它是一座死火山 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Since its discovery in the 1970s, it's been declared extinct 211 00:19:33,134 --> 00:19:34,469 等等 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Hang on. 212 00:19:34,636 --> 00:19:36,638 好像是熔岩流 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}These look like lava flows. 213 00:19:36,804 --> 00:19:41,676 但是任何熔岩流早就该静止了，在陨石撞击下都会被毁灭 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But any sign of lava should be long gone. obliterated by meteorite craters 214 00:19:41,843 --> 00:19:48,049 除非这个怪物没有死，只是休眠了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unless, this monster isn't dead, just sleeping 215 00:19:49,117 --> 00:19:52,654 火星的坚硬地表下可能有岩浆 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There could be magma flowing beneath the crust right now... 216 00:19:52,820 --> 00:19:56,124 积累着，等待喷发的一刻 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...building up, waiting to be unleashed 217 00:19:56,524 --> 00:20:00,294 火山活动会融化土壤里的冰冻水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Volcanic activity could be melting frozen water in the soil... 218 00:20:00,461 --> 00:20:04,599 将气体充入大气中 循环利用矿物质和养分， {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...pumping gases into the atmosphere, recycling minerals and nutrients 219 00:20:04,766 --> 00:20:09,971 创造出适合生命生存的环境 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Creating all the conditions needed for life 220 00:20:12,240 --> 00:20:18,346 这让美国大峡谷看起来像是人行道上一条裂缝 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This makes the Grand canyon look like a crack in the sidewalk 221 00:20:18,813 --> 00:20:20,415 无尽的荒凉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Endless desolation... 222 00:20:20,581 --> 00:20:26,754 长度足以横跨北美洲 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...so vast it would stretch all the way across North America. 223 00:20:29,190 --> 00:20:35,596 但是这里有活动的迹象：侵蚀 看起来像干涸的河床 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But here, signs of activity, erosion, and what looks like dried up river beds 224 00:20:35,763 --> 00:20:38,966 也许是火山活动融化了土壤中的冰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe volcanic activity melted ice in the soil... 225 00:20:39,133 --> 00:20:42,303 形成洪水冲出巨大峡谷 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...sending water gushing through this canyon. 226 00:20:42,470 --> 00:20:48,609 可能地下火山仍在融冰成水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Underground volcanoes could still be melting ice, creating water 227 00:20:48,776 --> 00:20:52,647 哪里有水，那里就可能会有生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And where there's water, there could be life 228 00:20:58,286 --> 00:21:01,956 搜寻生命的前锋就是这个简陋的家伙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The hunt for life is spearheaded by this humble fellow... 229 00:21:02,123 --> 00:21:04,859 美国宇航局的机遇号火星漫游车 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the NASA rover, Opportunity. 230 00:21:05,026 --> 00:21:07,028 它找到的证据证明这些贫瘠的平原 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's finding evidence that these barren plains... 231 00:21:07,195 --> 00:21:11,933 曾是古代湖泊或海洋 这些有水的地方可能会藏匿着生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...were once ancient lakes or oceans that could have harbored life 232 00:21:31,385 --> 00:21:33,521 看看这些山沟 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Look at those gullies. 233 00:21:36,057 --> 00:21:40,027 火星轨道探测器总能发现一些新的山沟 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Probes orbiting Mars keep spotting new ones. 234 00:21:41,863 --> 00:21:45,733 这进一步证明火星仍活蹦乱跳 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}More proof that Mars is alive and kicking 235 00:21:46,701 --> 00:21:49,337 也许是火星地表之下的水正在流淌 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...that water is flowing beneath its surface right now 236 00:21:49,504 --> 00:21:52,707 水可能维持火星上的生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Water that could be sustaining Martian life 237 00:21:57,779 --> 00:22:01,349 现在我们要做的就是找到这些生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Now, all we have to do is find it 238 00:22:06,788 --> 00:22:11,492 或许我们已经找到了，不是在火星，而是在地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe we've already found what we're looking for on Earth 239 00:22:11,659 --> 00:22:17,198 有人认为生命起源于火星，后来迁移到地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Some think that life started here and then migrated to Earth 240 00:22:20,768 --> 00:22:24,038 可能是一颗小行星撞击火星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}An asteroid impact could've blasted fragments of Mars... 241 00:22:24,205 --> 00:22:27,975 使得包含微生物的火星碎片飞向太空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...complete with tiny microbes out into space... 242 00:22:28,142 --> 00:22:32,647 进入年轻的地球 在地球上播种下生命的种子 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and onto the young Earth where they sowed the seeds of life 243 00:22:33,347 --> 00:22:39,854 难怪我们觉得火星那么迷人 它可能就是我们祖先的家园 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}No wonder we find Mars fascinating, this could be our ancestral home 244 00:22:40,755 --> 00:22:45,293 我们可能都是火星人 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It could be we are all Martians 245 00:22:47,562 --> 00:22:50,064 我们熟知的火星远去了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Mars we thought we knew is gone... 246 00:22:50,231 --> 00:22:54,902 取而代之是这个活跃变化的新行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...replaced by this new, active, changing planet. 247 00:22:57,905 --> 00:23:01,242 如果我们连我们的隔壁邻居火星都不了解, {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And if we don't know Mars, our next door neighbor... 248 00:23:01,409 --> 00:23:05,546 我们怎么能想象前方的惊奇? {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...how can we even imagine what surprises lie ahead 249 00:23:09,150 --> 00:23:12,954 我们的方向指向宇宙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our compass points across the cosmos... 250 00:23:14,188 --> 00:23:18,092 回到140亿年前 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...back in time 14 billion years... 251 00:23:19,360 --> 00:23:22,096 创世的那一刻 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to the moment of creation. 252 00:23:31,672 --> 00:23:33,941 此情此景开始让人害怕 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is getting scary. 253 00:23:36,410 --> 00:23:40,147 就像置身于一个巨大的视频游戏 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's like being inside a giant video game 254 00:23:43,985 --> 00:23:46,787 但这些也是真实的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But these are all too real. 255 00:23:47,154 --> 00:23:52,126 小行星，其中有些有数百英里宽 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Asteroids, some of them hundreds of miles wide 256 00:23:54,095 --> 00:23:57,865 这个约有20英里长 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This one must be about 20 miles long. 257 00:23:58,032 --> 00:24:03,471 你看，上面有个空间探测器 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And there, perched on it, a space probe. 258 00:24:05,006 --> 00:24:06,073 降落在一个时速达5万英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Can't have been easy... 259 00:24:06,240 --> 00:24:10,745 的小行星上可不是件容易的事 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...parking on an asteroid traveling at 50,000 miles an hour. 260 00:24:10,912 --> 00:24:14,415 我们一直在努力研究这些碎石 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's a lot of effort just to investigate some rubble. 261 00:24:14,582 --> 00:24:16,617 碎石之间经常碰撞 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Rubble that regularly collides... 262 00:24:16,784 --> 00:24:21,355 碎片后来落在地球上，就形成了地球上看到的陨石 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...breaks up and rains down on Earth as meteorites. 263 00:24:22,957 --> 00:24:27,795 我们的古人把流星雨看做是魔法的征兆 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our ancestors saw shooting stars as magical omens. 264 00:24:27,962 --> 00:24:29,897 他们是对的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And they were right 265 00:24:30,831 --> 00:24:33,634 就是这样一些碎石聚在一起就会形成行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Rubble like this came together to make the planets... 266 00:24:33,801 --> 00:24:35,937 包括我们的地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...including our own 267 00:24:36,404 --> 00:24:38,339 多美的魔法 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Pretty magical. 268 00:24:39,407 --> 00:24:41,676 通过测定地球上发现的陨石年龄 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}By dating the meteorites found on Earth 269 00:24:41,842 --> 00:24:47,081 我们知道行星诞生于45亿年前 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...we can tell the planets were born 4.6 billion years ago. 270 00:24:47,248 --> 00:24:51,953 这些殒石是我们太阳系的出生证明 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}These are the birth certificates of our solar system. 271 00:24:55,389 --> 00:24:59,694 但有些原因导致这些岩石没有形成行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}For some reason, these rocks didn't form into a planet 272 00:25:03,397 --> 00:25:05,933 一定是什么阻止了他们 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Something must have stopped them 273 00:25:06,100 --> 00:25:08,569 某种强大的力量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Something powerful. 274 00:25:17,712 --> 00:25:19,480 木星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Jupiter. 275 00:25:19,647 --> 00:25:21,615 犹如巨大的怪物 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}What a monster 276 00:25:21,782 --> 00:25:24,585 至少比地球的大1000倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}At least a thousand time bigger than Earth... 277 00:25:24,752 --> 00:25:29,223 大到可以装下太阳系其它所有行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...so vast you could fit all the other planets inside it 278 00:25:29,724 --> 00:25:34,095 木星的巨大体积对它周围产生很大的影响 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Something this massive dominates its neighbors 279 00:25:34,261 --> 00:25:38,165 它的引力正在把这些小行星形成扯开 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its gravity is pulling the asteroids apart 280 00:25:42,269 --> 00:25:44,505 真是美极了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And it's breathtaking 281 00:25:49,844 --> 00:25:52,613 但这个美人是个巨兽 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But this beauty is a beast. 282 00:25:54,815 --> 00:25:56,250 木星几乎都是由气体构成的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's almost all gas. 283 00:25:56,417 --> 00:26:01,255 如果在这里着陆，我们会径直穿过它的外层一去不复返 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Land here and we'd sink straight through its layers into oblivion. 284 00:26:08,329 --> 00:26:10,297 木星的美丽面孔是 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And Jupiter's good looks? 285 00:26:10,464 --> 00:26:14,135 它极端狂暴的产物 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The product of ferocious violence 286 00:26:14,301 --> 00:26:16,470 木星自转极快 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's spinning at an incredible rate 287 00:26:16,637 --> 00:26:20,441 卷起时速数百英里的飓风 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...whipping up winds to hundreds of miles an hour... 288 00:26:20,808 --> 00:26:25,613 把云层扭曲成条状和大大小小的漩涡 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...contorting the clouds into stripes eddies, whirlpools... 289 00:26:26,680 --> 00:26:31,218 这就是传说中的大红斑 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and this, the legendary Great Red Spot 290 00:26:32,953 --> 00:26:36,791 它是太阳系中最大、最猛烈的风暴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The biggest, most violent storm in the solar system. 291 00:26:36,957 --> 00:26:42,396 至少有地球的3倍大 已经肆虐了超过300年了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}At least three times the size of Earth, it's been raging for over 300 years 292 00:26:45,699 --> 00:26:50,538 这些翻腾的云产生闪电雷暴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}All these churning clouds must have sparked an electrical storm 293 00:26:53,040 --> 00:26:57,311 任何一个闪电都比我们地球上的强一万倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Just one bolt is 10,000 times more intense than any at home. 294 00:27:08,522 --> 00:27:14,361 远观眺望才是最好最安全的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Looks like the safest place to see Jupiter is from a distance 295 00:27:15,162 --> 00:27:16,730 在它的两极 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Up there at the poles... 296 00:27:16,897 --> 00:27:21,068 那些光就像我们地球的极光一样在翩翩起舞 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...those dancing lights, they're like the auroras back home. 297 00:27:24,472 --> 00:27:26,440 但盖格计数器的读数开始发狂 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But the Geiger counter is going wild 298 00:27:26,607 --> 00:27:31,612 致命辐射产生的光看起来也是能致人死地 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Even these are deadly, generated by lethal radiation 299 00:27:38,519 --> 00:27:41,856 太空中凡事不可貌相 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Out here, nothing is what it seems. 300 00:27:45,159 --> 00:27:50,698 宇宙充满了恐怖和陷阱 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The universe is full of terrors, traps. 301 00:27:56,670 --> 00:28:01,108 也许这个五彩缤纷的木卫一是一个避风港 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe this is a safe haven, the multi-colored moon, Io 302 00:28:14,321 --> 00:28:15,456 错了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Wrong 303 00:28:15,623 --> 00:28:17,124 大错特错 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Very wrong. 304 00:28:17,291 --> 00:28:23,197 那些闪亮的颜色是融岩、火山喷出的岩浆 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Those brilliant colors are molten rock, volcanoes spewing lava. 305 00:28:30,304 --> 00:28:35,543 我们神奇的宇宙之旅开始变成了生存之战 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our journey across the universe is turning into a struggle for survival 306 00:28:35,709 --> 00:28:38,279 我们曾希望只要战胜这些危险 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We've got to hope that if we outlast the dangers... 307 00:28:38,445 --> 00:28:44,285 我们就会看到无法想象的奇观 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...we'll be rewarded by wonders beyond imagination 308 00:28:51,425 --> 00:28:54,495 离开地球4亿英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Four hundred million miles from Earth... 309 00:28:54,662 --> 00:28:59,400 搭乘民航航班要飞一个世纪 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...flying a commercial airliner here would take nearly a century 310 00:29:02,836 --> 00:29:05,706 多么古怪的地方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}What a weird looking place... 311 00:29:07,708 --> 00:29:10,110 不可思议的是，它看起来又是那么熟悉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and yet, strangely familiar 312 00:29:10,277 --> 00:29:15,883 所有的冰、山脊和裂缝 都与北极有点相似 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A bit like the Arctic, with all that ice, all those ridges and cracks 313 00:29:20,020 --> 00:29:23,490 它是木星的卫星 木卫二 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's Jupiter's moon, Europa. 314 00:29:23,657 --> 00:29:29,430 也许真的很像北极 冰块漂浮在液态水上 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And maybe, like the Arctic, this ice is floating on water, liquid water 315 00:29:32,399 --> 00:29:35,903 但是这里距离太阳有5亿英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But we're half a billion miles from the Sun. 316 00:29:36,203 --> 00:29:39,406 当然，木卫二是冰冻固体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Surely, Europa is frozen solid 317 00:29:45,679 --> 00:29:50,517 除非木星的引力在它内部造成摩擦 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unless, Jupiter's gravity is creating friction deep inside... 318 00:29:50,684 --> 00:29:54,989 使冰融化，允许生命在它的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...heating the ice into water, allowing life to develop in the water... 319 00:29:55,155 --> 00:29:57,758 冰冻外壳下的水中发展 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...beneath its frozen crust. 320 00:29:58,692 --> 00:30:01,895 我们距离外星生物也许只有几英尺远 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We might be feet away from aliens 321 00:30:03,430 --> 00:30:09,036 下面有微生物、甲克类，甚至有乌贼构成的生态系统 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}From a whole ecosystem of microbes, crustaceans, maybe even squid 322 00:30:09,203 --> 00:30:13,274 我们和这些可能存在的外星生物之间 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The only thing between us and the possibility of alien life... 323 00:30:13,440 --> 00:30:16,043 只隔着一层薄薄的冰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...this layer of ice. 324 00:30:17,478 --> 00:30:20,147 在我们派出飞船钻透它的冰层之前 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But until we send a spacecraft to drill here... 325 00:30:20,314 --> 00:30:25,386 木卫二仍会一直保守它的秘密 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...Europa's secrets will remain beyond reach 326 00:30:42,202 --> 00:30:48,108 它挑逗着我们的想象 萦绕在我们梦中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's captivated our imaginations, haunted our dreams 327 00:30:48,509 --> 00:30:53,247 现在它就在我们面前自转 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And here it is, spinning before our eyes 328 00:30:53,414 --> 00:30:54,682 土星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Saturn. 329 00:30:54,848 --> 00:30:56,050 由古罗马农神的名字命名 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Named for the Roman god... 330 00:30:56,216 --> 00:31:00,054 他曾统治过一个祥和安宁的黄金时代 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...who reigned over an golden age of peace and harmony 331 00:31:04,725 --> 00:31:11,231 这个行星是一个巨大的气体球 轻到可以漂浮在水面上 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This planet's a giant ball of gas, so light it would float on water 332 00:31:12,132 --> 00:31:17,037 壮观的土星环展开的长度几乎等于地球到月球的距离 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its spectacular rings would stretch almost from Earth to the Moon. 333 00:31:22,776 --> 00:31:24,578 那是卡西尼探测器 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's the Cassini orbiter 334 00:31:24,745 --> 00:31:27,214 它收到鬼魅般的无线电信号 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's picking up ghostly radio emissions 335 00:31:27,381 --> 00:31:31,352 可能是由土星两极的极光产生的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Probably generated by auroras around Saturn's poles 336 00:31:31,518 --> 00:31:34,655 这是真正的天体音乐 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is the real music of the spheres. 337 00:31:39,093 --> 00:31:42,129 卡西尼告诉我们这些土星环的来历 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Cassini's telling us where these rings came from. 338 00:31:42,296 --> 00:31:47,134 它们是被土星引力撕碎的卫星残骸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They're the remnants of a moon shattered by Saturn's gravitational pull 339 00:31:48,068 --> 00:31:53,207 彻底毁灭产生的无比美景 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Incomparable beauty from total destruction 340 00:32:04,017 --> 00:32:05,252 无数的碎坚冰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Billions of shards of ice 341 00:32:05,419 --> 00:32:10,324 有些很小，就像冰块，有些则有房子那么大 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Some as small as ice cubes, others the size of houses. 342 00:32:13,660 --> 00:32:17,631 他们碰撞、破碎、重新聚集 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They collide, break apart, reassemble 343 00:32:21,402 --> 00:32:25,038 就是我们太阳系的早期快照 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's like a snapshot of our early solar system... 344 00:32:25,672 --> 00:32:28,542 尘埃和气体环绕着初生的太阳 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...as dust and gas orbited the newly born Sun 345 00:32:28,709 --> 00:32:31,779 然后引力施展魔力 吸引碎块聚在一起 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and gravity worked this magic pulling the lumps together... 346 00:32:31,945 --> 00:32:37,918 直到这些碎块形成地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...until from space trash like this, our home emerged 347 00:32:44,725 --> 00:32:47,194 我们可以一直呆在这里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We could stay here forever 348 00:32:56,403 --> 00:33:01,308 但我们还要赶路，还有很多东西要看 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But there's so much further to go, so much more to see. 349 00:33:02,576 --> 00:33:07,915 土卫六 被厚云笼罩着 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like this moon wrapped in thick clouds, Titan. 350 00:33:31,905 --> 00:33:34,708 它有大气层 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's an atmosphere down here 351 00:33:34,875 --> 00:33:39,146 有风、雨，甚至有季节 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's wind, rain ,even seasons 352 00:33:39,313 --> 00:33:42,816 有河流、湖泊和海洋 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Rivers, lakes and oceans 353 00:33:43,784 --> 00:33:47,955 看起来和地球很像 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It looks so familiar, so similar to Earth. 354 00:33:53,160 --> 00:33:57,764 但那不是水，是液态天然气 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But that's not water, it's liquid natural gas 355 00:33:57,931 --> 00:34:03,937 这里天然气比我们地球的油气储量多几百倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Hundreds of times more natural gas than all the Earth's oil and gas reserves 356 00:34:05,639 --> 00:34:09,877 或许有一天 我们把它当做一个燃料基地 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe, one day, we'll use this energy to fuel a colony. 357 00:34:11,979 --> 00:34:14,915 假设土卫六上早已没有生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Assuming there isn't life here already 358 00:34:22,055 --> 00:34:26,460 惠更斯号探测器在这里寻找答案 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Huygens space probe is here to find out 359 00:34:27,928 --> 00:34:32,032 它报告说土卫六的土壤中存在有机成分 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's telling us there's organic material in the soil. 360 00:34:33,267 --> 00:34:37,638 但这儿太冷了，低到零下300度(华氏) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But it's so cold, minus 300 degrees 361 00:34:38,906 --> 00:34:41,742 生命无法发展 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's no way life could develop 362 00:34:42,409 --> 00:34:45,145 除非土卫六变暖 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unless Titan warms up. 363 00:34:47,080 --> 00:34:49,283 有人预言太阳会变得越来越热 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Sun is supposed to get hotter 364 00:34:49,449 --> 00:34:52,519 真是这样，也许这里会出现生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}When it does maybe life will spring up here... 365 00:34:52,686 --> 00:34:55,088 就像数十亿年前的地球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...just like it did on Earth 366 00:34:57,824 --> 00:35:03,697 当地球热到我们不能居住的时候，或许我们可以搬到土卫六 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And as the Earth gets too hot for us, maybe we'll move to Titan. 367 00:35:05,465 --> 00:35:09,536 到那时，也许我们就会把这个遥远的地方称为家 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}One day, we might call this distant land home 368 00:35:17,878 --> 00:35:19,379 家 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Home. 369 00:35:19,546 --> 00:35:23,317 离我们至少7亿英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're at least 700 million miles away now. 370 00:35:23,483 --> 00:35:27,387 过了这个点，我们就看不见地球了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}After this we lose visual contact with Earth. 371 00:35:28,555 --> 00:35:30,657 我们正站在悬崖边上 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're standing on a cliff 372 00:35:30,824 --> 00:35:35,562 眺望着通往时间起点的巨大深渊 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Looking out over a great chasm that stretches to the beginning of time. 373 00:35:35,896 --> 00:35:39,733 我们有勇气跳下去吗？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Do we have the courage to jump? 374 00:35:42,069 --> 00:35:45,505 我们在太阳系的外围 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're in the solar system's outer reaches. 375 00:35:46,473 --> 00:35:50,677 在地球上看不得这里，古人不知道这里的存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unseen from Earth, unknown for most of history 376 00:35:51,111 --> 00:35:54,748 就像潜入深海 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's like diving into the depths of the ocean 377 00:36:04,725 --> 00:36:09,896 那些光环，天王星的倾斜的自转轴看起来似乎 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Those rings make it look like Uranus has been tilted off its axis 378 00:36:10,063 --> 00:36:13,033 被游荡的行星给弄偏了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...toppled over by a stray planet 379 00:36:17,170 --> 00:36:19,339 这里让人毛骨悚然 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's eerie out here. 380 00:36:19,906 --> 00:36:24,077 让人开始感觉渺小、孤独 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Already beginning to feel small, lonely 381 00:36:24,878 --> 00:36:28,915 或许在宇宙边缘我们就会有这种感觉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe this is how we'll feel at the edge of the universe 382 00:36:32,886 --> 00:36:35,922 但是我们才出发不远 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But we've barely left the shore 383 00:36:37,858 --> 00:36:44,364 如果太阳系宽度是1英里，我们才走了3英寸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}If the solar system was one mile wide, so far we've traveled about 3 inches 384 00:36:57,344 --> 00:37:00,914 太空深处出现了另一个怪售 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Out of the deep, another strange beast... 385 00:37:01,081 --> 00:37:06,219 海洋之神 - 海王星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the god of the sea, Neptune 386 00:37:09,289 --> 00:37:12,959 一个被甲烷包围着的世界 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This world is covered in methane gas 387 00:37:14,327 --> 00:37:16,730 平均时速1000英里的飓风 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And a storm as big as Earth... 388 00:37:16,897 --> 00:37:21,201 形成一个像地球一样大的风暴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...whipped up by savage thousand mile-an-hour winds 389 00:37:21,735 --> 00:37:25,105 地球上的风是由太阳照射引起的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Back home, it's the Sun that drives the wind... 390 00:37:25,272 --> 00:37:26,773 海王星离太阳太远了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...But Neptune's far away. 391 00:37:26,940 --> 00:37:31,611 一定是什么东西造成这些暴风 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Something else must be creating these ferocious winds 392 00:37:33,947 --> 00:37:35,582 会是什么呢？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But what? 393 00:37:37,718 --> 00:37:41,154 我们对太阳系所知甚少 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We know very little about our own solar system. 394 00:37:52,365 --> 00:37:56,203 经过那几个气体星球后，终于找到了一个固体卫星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}After all those balls of gas a solid moon 395 00:37:58,939 --> 00:38:00,540 海卫一 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...Triton. 396 00:38:02,175 --> 00:38:06,179 固体的，但不稳定 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Solid but not stable 397 00:38:09,883 --> 00:38:11,218 看看这些间歇泉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Just look at those geysers... 398 00:38:11,384 --> 00:38:16,089 仿佛喷出奇怪烟尘的宇宙烟囱 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...cosmic smokestacks pumping out strange soot. 399 00:38:16,623 --> 00:38:18,959 海卫一绕海王星旋转的方向 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And this moon is revolving around Neptune 400 00:38:19,126 --> 00:38:22,329 与海王星自转方向相反 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...in the opposite direction of the planet's spin. 401 00:38:22,496 --> 00:38:25,098 一场意志的宇宙之战 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A cosmic battle of wills... 402 00:38:25,265 --> 00:38:29,703 这颗愤怒的卫星难逃一劫 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...that this angry moon is destined to lose 403 00:38:30,771 --> 00:38:34,407 海王星巨大的引力正在拉扯着海卫一 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Neptune's massive gravity is pulling on Triton. 404 00:38:34,574 --> 00:38:38,211 使它慢下来，靠近海王星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Slowing it down, reeling it in 405 00:38:41,715 --> 00:38:46,453 总有一天，海卫一会被海王星撕碎 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}One day, it will be ripped apart by Neptune 406 00:38:49,623 --> 00:38:51,291 就这样了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And that's it 407 00:38:51,458 --> 00:38:55,929 我们太阳系里再也没有任何别的卫星和行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}No more moons, no more planets in our solar system. 408 00:38:56,096 --> 00:38:59,666 温度越来越低 我们距离太阳越来越远 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's getting colder, we're getting further from the Sun... 409 00:38:59,833 --> 00:39:03,904 慢慢脱离太阳引力的束缚 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...slipping from the grip of its gravitational tentacles. 410 00:39:05,906 --> 00:39:08,341 但这里并非空的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But this isn't a void 411 00:39:08,508 --> 00:39:12,612 这里充满着冻结的岩石 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's teeming with frozen rocks. 412 00:39:13,613 --> 00:39:15,515 就像冥王星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like Pluto. 413 00:39:15,682 --> 00:39:18,885 直到不久前，我们还以为冥王星是孤零零的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Until recently, we thought Pluto was alone. 414 00:39:19,052 --> 00:39:21,388 在它之外就没有什么了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Beyond it, nothing 415 00:39:22,122 --> 00:39:23,857 但我们错了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We were wrong 416 00:39:24,024 --> 00:39:26,426 还有更多的冰冻世界 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}More frozen worlds 417 00:39:26,960 --> 00:39:31,164 我们连怎么称呼这些最新发现都无法达成一致 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Discoveries so new nobody can agree what to call them 418 00:39:31,331 --> 00:39:36,269 小冥王星、冰矮星、类QB1天体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Plutinos, ice dwarves, cubewanos 419 00:39:39,139 --> 00:39:44,578 我们的太阳系不是我们曾经想象的那个整洁干净 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our solar system is far more chaotic and strange than we had imagined 420 00:39:45,212 --> 00:39:48,715 现在我们距离地球超过80亿英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Now we're 8 billion miles from home. 421 00:39:49,950 --> 00:39:53,887 已发现的距离太阳最远的绕日天体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The most distant thing ever seen that orbits the Sun... 422 00:39:54,054 --> 00:40:00,560 另一个小型的冰冷世界 发现于2003年，被称为赛德娜（小行星90377） {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...another small, icy world, Sedna, discovered in 2003 423 00:40:01,661 --> 00:40:05,432 它绕日一周需要1万年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its orbit takes 10,000 years to complete. 424 00:40:11,271 --> 00:40:15,108 等一下 这里还有别的东西 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Hang on, there's something else out here. 425 00:40:16,676 --> 00:40:21,615 旅行者1号星际探测器 已经飞行了100亿英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Ten billion miles from home the space probe, Voyager 1. 426 00:40:23,016 --> 00:40:25,719 它的这些铝和天线 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This bundle of aluminum and antennae... 427 00:40:25,886 --> 00:40:29,155 使我们能够获得那些巨大行星的近照 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...gave us close up views of the giant planets... 428 00:40:29,322 --> 00:40:32,993 了解它们那些奇异的卫星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and discovered many of their strange moons. 429 00:40:35,028 --> 00:40:41,468 旅行者1号的速度比子弹快20倍 不断的向地球发送信息 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's traveling 20 times faster than a bullet, sending messages home 430 00:40:50,210 --> 00:40:51,645 那个黄金板 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}That gold plaque... 431 00:40:51,811 --> 00:40:54,948 一个星际玻璃樽 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...its a kind of intergalactic message in a bottle. 432 00:40:55,115 --> 00:40:57,584 上面录有各种语言的问候 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A greeting record in different languages 433 00:41:06,559 --> 00:41:11,531 还有一副地图，标明如何找到我们的太阳系 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And a map showing how to find our home solar system 434 00:41:13,500 --> 00:41:15,335 伟大的物理学家斯蒂芬霍金 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The great physicist, Stephen Hawking... 435 00:41:15,502 --> 00:41:18,905 认为这样的热情好客是一个错误 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...thinks it was a mistake to roll out the welcome mat. 436 00:41:19,072 --> 00:41:25,011 毕竟如果我们身处丛林，大声呼喊是否明智？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}After all, if you're in the jungle, is it wise to call out? 437 00:41:38,058 --> 00:41:41,528 他们很像我们先前看到的彗星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}These comets look like the ones we saw earlier. 438 00:41:41,695 --> 00:41:45,699 有理论认为生命的原始材料产自这里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's a theory that the raw materials for life began out here... 439 00:41:45,865 --> 00:41:49,202 直到什么东西动到了它 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...on a rock like this until something dislodged it... 440 00:41:49,369 --> 00:41:52,439 使之朝着地球飞去 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...sending it hurting towards the Earth 441 00:41:55,375 --> 00:42:00,714 也许地球上的水就是我们看到这些冰块带去的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And seeding all this ice, maybe comets carried water to Earth too 442 00:42:01,481 --> 00:42:04,751 海洋里的、你身体里的水 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The water in the oceans, in your body... 443 00:42:04,918 --> 00:42:08,755 都来自这个遥远的宇宙制冰机 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...all from this distant celestial ice machine. 444 00:42:14,761 --> 00:42:20,467 我们离地球5万亿英里，也就是5兆英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're 5 million, million, that's 5 trillion miles from home. 445 00:42:20,633 --> 00:42:23,136 但这还只是一小步 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But this is still only a baby step. 446 00:42:23,303 --> 00:42:27,974 前面还有好几兆英里，数十亿颗恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Ahead, trillions of miles, billions of stars. 447 00:42:28,141 --> 00:42:31,244 我们该停止向后看而要向前看 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Time to stop looking back and start looking ahead... 448 00:42:31,411 --> 00:42:36,282 踏进巨大无垠的宇宙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to step out into the big, wide universe 449 00:42:49,362 --> 00:42:51,865 星际空间 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Interstellar space. 450 00:42:59,506 --> 00:43:02,042 数十亿颗像我们太阳一样的恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Billions of stars like our own Sun... 451 00:43:02,208 --> 00:43:06,679 很多有行星 很多行星有卫星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...many with planets, many of those with moons. 452 00:43:13,453 --> 00:43:16,222 不知道该选择哪条路了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's hard to know which way to go 453 00:43:16,389 --> 00:43:19,426 存在着无限的可能性 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There are infinite possibilities. 454 00:43:21,895 --> 00:43:25,465 我们需要强大的加速度 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're going to need a serious burst of acceleration. 455 00:43:50,123 --> 00:43:53,026 距离地球25兆英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Twenty-five trillion miles from home. 456 00:43:53,193 --> 00:43:57,597 乘坐太空飞船要飞15万年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A 150,000-year ride in the space shuttle. 457 00:43:57,831 --> 00:44:02,102 然而我们只是抵达了距离我们最近的其他太阳系 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And we're only just reached the first solar system beyond 458 00:44:04,204 --> 00:44:06,406 半人马座α星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...Alpha Centauri 459 00:44:07,874 --> 00:44:10,243 不是一颗，而是三颗恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Not one but three stars. 460 00:44:10,410 --> 00:44:14,447 它们互相围绕公转，形成一场宇宙对决 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Spinning around each other locked in a celestial standoff 461 00:44:14,614 --> 00:44:17,183 每颗恒星都吸引的另一颗 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Each star's gravity attracting the other... 462 00:44:17,350 --> 00:44:21,087 他们极快的轨道速度使它们能够保持距离 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...their blazing orbital speed keeping them apart. 463 00:44:29,863 --> 00:44:34,434 进入它们之间 我们会在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Get between them and we'd be vaporized... 464 00:44:35,101 --> 00:44:37,670 距离地球几兆英里的地方被蒸发 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...trillions of miles from home. 465 00:44:38,171 --> 00:44:41,441 这么远的距离，英里已经变得无用了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So far that miles are becoming meaningless. 466 00:44:41,608 --> 00:44:44,978 我们在这里得使用光年计算 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Out here, we measure in light years. 467 00:44:48,481 --> 00:44:52,418 光一年可以飞行6兆英里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Light travels 6 trillion miles a year... 468 00:44:52,685 --> 00:44:56,389 我们已经离开地球4光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...so we are overfour light-years from home. 469 00:45:00,026 --> 00:45:05,098 远到我们几乎无法理解的距离 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Distances so vast they're mind-boggling 470 00:45:10,370 --> 00:45:12,906 谁知道前方会是什么样的奇异世界 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Who knows what strange forces lie ahead 471 00:45:13,072 --> 00:45:15,041 如果我们抵达了宇宙边缘， {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...what we'll discover when-- 472 00:45:15,208 --> 00:45:19,779 我们会发现什么呢？ {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}If we reach the edge of the universe 473 00:45:24,517 --> 00:45:30,290 天苑四恒星距离地球10光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Ten light years from Earth, the star Epsilon Eridani 474 00:45:31,057 --> 00:45:34,260 它有由尘埃和冰构成的壮观圆环 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Spectacular rings of dust and ice 475 00:45:34,427 --> 00:45:38,231 在圆环里的某些地方 有碎片形成的行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And somewhere in there, planets forming out of debris... 476 00:45:38,398 --> 00:45:41,634 就在我们眼前诞生 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...being born before our eyes. 477 00:45:49,142 --> 00:45:53,413 到处都是小行星和彗星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Asteroids and comets everywhere 478 00:45:57,550 --> 00:46:00,353 我们几乎就是看到了数十亿年前的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We could almost be looking at our own solar system... 479 00:46:00,520 --> 00:46:02,255 我们太阳系的样子 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...billions of years ago. 480 00:46:02,422 --> 00:46:05,325 彗星把生命材料带到 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}With comets delivering the building blocks of life... 481 00:46:05,491 --> 00:46:07,961 这些年轻的行星上 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to these young planets. 482 00:46:27,280 --> 00:46:31,918 主导这些行为的是一个比我们太阳小一些的恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}At the center of all the action, a star smaller than our sun... 483 00:46:32,085 --> 00:46:34,621 这颗恒星还处于幼年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...still in its infancy. 484 00:46:34,787 --> 00:46:39,325 这个太阳系的生命应该还很原始 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Any life in this solar system would be primitive at best 485 00:46:47,100 --> 00:46:50,903 这里应该还有更成熟更进化的太阳系 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There must be more mature solar systems out here... 486 00:46:51,070 --> 00:46:55,408 但是找到它们却像在宇宙海洋里捞针 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...But finding them is like looking for a needle in a cosmic haystack 487 00:47:04,617 --> 00:47:07,320 距离地球20光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Twenty light years from Earth. 488 00:47:09,155 --> 00:47:12,225 红矮星格雷司 581 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Star Gliese 581 489 00:47:17,363 --> 00:47:20,466 它大概和我们的太阳同龄 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's about the same age as our sun. 490 00:47:29,409 --> 00:47:33,179 这颗行星距离它的太阳距离刚刚好 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This planet is just the right distance from its sun 491 00:47:33,680 --> 00:47:39,352 再近一点水会蒸发，再远一点则会结成冰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Any closer and water would boil away, any further and it would freeze 492 00:47:40,019 --> 00:47:43,556 一个生命演化的理想环境 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Ideal conditions for life to emerge 493 00:47:49,062 --> 00:47:53,900 如果彗星的撞击给它带去水和有机原料 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And if a comet has struck, delivering water and organic materials... 494 00:47:54,067 --> 00:47:59,605 那么生命、像我们一样的复杂生物 甚至像我们一样的文明 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...then life, complex beings like us, even civilizations like our own... 495 00:47:59,772 --> 00:48:03,109 现在就可能在这里存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...could be down there right now 496 00:48:08,047 --> 00:48:11,017 他们可能正调到我们的电视信号 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They could be tuning into our TV signals... 497 00:48:11,184 --> 00:48:14,354 观看我们20年前的电视节目 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...watching shows from 20 years ago. 498 00:48:21,227 --> 00:48:23,663 但是在我们找到跨越这么远距离的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But until we devise a way of communicating... 499 00:48:23,830 --> 00:48:29,402 通讯方法之前 我们只能猜测 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...over these vast distances, all we can do is speculate 500 00:48:30,069 --> 00:48:33,473 我们和他们各自的生存着 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Us and them, living parallel lives... 501 00:48:33,639 --> 00:48:36,876 彼此都不知道对方的存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...unaware of each other's existence. 502 00:48:42,181 --> 00:48:46,552 除非这里曾有过生命和灭绝 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Unless life has come and gone 503 00:48:57,230 --> 00:48:59,732 那一定是彗星惹的祸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}That's the problem with comets. 504 00:48:59,899 --> 00:49:03,903 彗星是创造者，同是也是毁灭者 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They're creators and destroyers... 505 00:49:04,070 --> 00:49:07,707 就像恐龙的遭遇 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...as the dinosaurs the hard way 506 00:49:09,409 --> 00:49:12,111 这就是那根宇宙海洋里的针 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is the needle in the cosmic haystack... 507 00:49:12,278 --> 00:49:16,849 是最像我们太阳系的那样适宜生存的太阳系 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the closest we've come to a habitable solar system like our own... 508 00:49:17,016 --> 00:49:19,485 但这只是碰巧而已 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...but it's a chance encounter. 509 00:49:20,019 --> 00:49:21,154 宇宙中可能有上亿个 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There could be hundreds... 510 00:49:21,320 --> 00:49:27,026 类似的太阳系 也可能一个都没有 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...millions more solar systems like this out there or none at all. 511 00:49:37,770 --> 00:49:40,907 行星柏勒罗丰的大气层 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Some of the atmosphere on this planet, Bellerophon... 512 00:49:41,073 --> 00:49:44,944 正在被它附近的恒星蒸发掉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...is being boiled away by its nearby star. 513 00:49:56,422 --> 00:49:59,425 我们在地球看不到距离这么远的行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}From Earth, we can't see planets this far out. 514 00:49:59,592 --> 00:50:03,930 他们都被周围的恒星耀眼的光辉掩盖住了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They're obscured by the brilliance of their neighboring stars. 515 00:50:05,231 --> 00:50:09,535 不过行星对恒星施加微小的引力作用 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But the planets have a minute gravitational pull on those stars. 516 00:50:09,702 --> 00:50:14,707 通过测量的种微小移动我们就能证明这些行星的存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Measure these tiny movements and we can prove they exit 517 00:50:18,611 --> 00:50:22,882 我们就是这样在1990年代发现行星柏勒罗丰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}That's how we tracked down Bellerophon in the 1990's... 518 00:50:24,650 --> 00:50:27,954 还发现了数百颗其他遥远行星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and hundreds of other distant planets 519 00:50:32,792 --> 00:50:36,362 距离地球65光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Sixty-five light years from Earth... 520 00:50:36,863 --> 00:50:41,100 如果在这里打开电视 那么你会收看到希特勒的柏林奥运会 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...turn on your TV here and you'd pick up Hitler's Berlin Olympics 521 00:51:02,522 --> 00:51:05,291 双星 大陵五(英仙座β) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The twin stars of Algol. 522 00:51:05,458 --> 00:51:08,895 自古人们就称它为恶魔之星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Known to the ancients as the demon star 523 00:51:10,463 --> 00:51:15,868 当其中一个遮住另一颗时 从地球看就像在眨眼睛 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}From Earth, it appears to blink as one star passes across the other. 524 00:51:16,302 --> 00:51:18,905 近距离观察更奇怪 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Up close, it's even stranger. 525 00:51:19,071 --> 00:51:22,542 其中一颗恒星正被在另一颗吸引过去 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}One star is being sucked towards the other 526 00:51:26,812 --> 00:51:29,015 这里距离地球接近100光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Almost 100 light years from home... 527 00:51:29,181 --> 00:51:33,486 最早的无线电广播信号也只是模糊的低语 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...faint whispers from one of the first ever radio broadcasts 528 00:51:50,169 --> 00:51:54,307 从这里或更远的地方观察，地球似乎从来没有存在过 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}From here on out, it's as if the Earth never existed 529 00:51:59,445 --> 00:52:02,381 我们站在海滩 仰望天空，纳闷我们在哪里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Feels like a life time since we stood on that beach... 530 00:52:02,548 --> 00:52:08,454 这好像是上辈子的事情 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...looking up at the sky, wondering where and how we fit in 531 00:52:10,189 --> 00:52:13,359 有一点我们已经确认 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We've learned one thing for sure 532 00:52:13,526 --> 00:52:18,064 我们无法预测前方的宇宙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The universe is too bizarre, too startling... 533 00:52:18,564 --> 00:52:21,667 会是怎样的奇异和惊人 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...for us to guess what lies ahead 534 00:52:26,639 --> 00:52:31,410 在我们的星系深处 银河 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Deep inside our galaxy, the Milky Way 535 00:52:31,844 --> 00:52:36,582 一千零一夜唤起的一丝微光 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Pinpricks of light that have inspired a thousand and one tales 536 00:52:38,017 --> 00:52:43,456 七姊妹是古希腊擎天神亚特拉斯的女儿 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The Seven Sisters, the daughters of the ancient Greek god, Atlas 537 00:52:43,623 --> 00:52:46,559 她们变成星星来安慰 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...transformed into star to comfort their father... 538 00:52:46,726 --> 00:52:50,763 用肩膀扛起天空的父亲 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...as he held the heavens on his shoulders 539 00:52:57,036 --> 00:53:00,673 还有巨大的参宿四(猎户座α星) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And this giant, Betelgeuse 540 00:53:00,840 --> 00:53:04,377 我们至今为止看到的最大最亮的恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The brightest, biggest star we've seen so far. 541 00:53:04,543 --> 00:53:08,381 它至少比我们的太阳宽600倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Six hundred times wider than our sun 542 00:53:20,426 --> 00:53:24,930 但是这个不是恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But this, it's not a star... 543 00:53:27,600 --> 00:53:32,371 也不是行星，不像我们已经见过的任何东西 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...not a planet, not like anything we've seen. 544 00:53:40,813 --> 00:53:45,518 一个幽灵般的魅影 距离地球超过1300光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A ghostly

浓密的尘埃和气体包裹着我们 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Dust and gas shrouding us 547 00:54:06,105 --> 00:54:11,644 在暗云的深处 一个光球正吸引尘埃和气体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There, deep inside, a light, pulling the dust and gas towards it... 548 00:54:11,811 --> 00:54:16,549 加热融合成一个炙热的气体球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...heating up, merging into a ball of burning hot gas. 549 00:54:16,716 --> 00:54:21,420 就像一颗恒星，像一个迷你的太阳 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like a star, like our sun in miniature. 550 00:54:22,488 --> 00:54:24,757 它的内部有几百万度 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Inside, it's millions of degrees 551 00:54:24,924 --> 00:54:28,227 如此高的温度足以引发核反应 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So hot, it's beginning to trigger nuclear reactions... 552 00:54:28,394 --> 00:54:31,363 这种反应维持我们的太阳闪耀 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the kind that keep our sun shining... 553 00:54:31,530 --> 00:54:36,435 产生能量、辐射和光线 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...making energy, radiation, light 554 00:54:36,602 --> 00:54:40,372 一颗恒星正在诞生 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A star is being born. 555 00:54:58,057 --> 00:55:02,828 猎户座暗星云就是一座巨大的恒星工厂 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Orion's dark cloud is a vast star factory 556 00:55:06,599 --> 00:55:10,836 我们正在目睹未来宇宙的诞生 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're witnessing the birth of the future universe. 557 00:55:16,742 --> 00:55:19,812 我们原以为会遭遇毁灭 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We've come to expect destruction... 558 00:55:19,979 --> 00:55:24,316 但这是宇宙中最伟大的创造行为之一 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...but this is one of the universe's greatest acts of creation. 559 00:55:24,483 --> 00:55:26,385 恒星的诞生 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Star birth. 560 00:55:35,227 --> 00:55:38,030 好像不太对劲 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This doesn't look right 561 00:55:47,139 --> 00:55:52,511 气体喷流的巨大力量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Jets of gas exploding out with tremendous force... 562 00:55:52,678 --> 00:55:56,982 把尘埃和气体喷射到数百万英里之外

here, they'll take thousands of years to disperse 567 00:56:31,016 --> 00:56:34,954 它们看起来形成了巨大的星际雕像 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}They seem to be forming a vast stellar sculpture. 568 00:56:35,120 --> 00:56:39,325 大自然不只是科学家和工程师 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Nature is more than a scientist, an engineer... 569 00:56:39,491 --> 00:56:43,896 它是最大手笔的艺术家 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it's an artist on the grandest of scales 570 00:56:51,337 --> 00:56:56,141 这就是旷世杰作(猎户座马头星云) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And this is a masterpiece

{\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Do they die? 573 00:57:08,654 --> 00:57:12,992 它们死去时是悄无声息还是轰轰烈烈 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Do they slip quietly into the night or go out with a bang? 574 00:57:18,764 --> 00:57:24,236 答案就在这里到宇宙边缘的某些地方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Somewhere between here and the edge of the universe lies the answer. 575 00:57:29,742 --> 00:57:32,611 发光云 悬挂在太空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Luminous clouds, suspended in space... 576 00:57:32,778 --> 00:57:36,916 环绕着曾经类似我们太阳的恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...encircling what was once a star like our own sun. 577 00:57:38,617 --> 00:57:42,421 唯一剩下就是这些五彩亮丽的气体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}All that's left of it are these brightly colored gases... 578 00:57:42,588 -->

{\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...released into space on its death 580 00:57:49,828 --> 00:57:53,632 绿色和紫色的是氢和氦 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Green and violet, hydrogen and helium... 581 00:57:53,799 --> 00:57:57,002 它们是宇宙的原始原料 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the raw materials of the universe. 582 00:57:57,636 --> 00:58:00,706 红色和蓝色的是氮和氧 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Red and blue, nitrogen and oxygen... 583 00:58:00,873 --> 00:58:03,976 它们是构成地球生命的材料 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the building blocks of life on Earth 584 00:58:07,146 --> 00:58:11,784 为了我们的生存，这样的恒星必须死去 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}For us to live, stars like this had to die 585 00:58:13,786 --> 00:58:18,257 我们身体的每个原子都产自这些已经死亡的恒星核聚变 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Every atom in our body was produced by nuclear fusion... 586 00:58:19,024 --> 00:58:23,362 很久以后地球才诞生 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...in stars that died long before the Earth was even born. 587 00:58:24,663 --> 00:58:27,733 我们都是恒星材料 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We are all the stuff of stars 588 00:58:28,801 --> 00:58:33,439 我们的家谱溯源至此 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our family tree begins here 589 00:58:54,526 --> 00:58:58,897 云团的核心是恒星的鬼魂 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}At its heart, the ghost of a star... 590 00:58:59,531 --> 00:59:01,467 一颗白矮星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...a white swarf 591 00:59:01,633 --> 00:59:05,604 白色、炙热 体积很小 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}White, hot, small... 592 00:59:05,771 --> 00:59:08,574 但是密度却是高的难以置信 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...but unbelievably dense 593 00:59:09,141 --> 00:59:13,078 当恒星濒临死亡的时候 它的原子融合挤压在一起 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}In the star's dying moments, its atoms fused and squeezed together 594 00:59:13,245 --> 00:59:19,752 让它变得密度极高，一茶匙白矮星的物质就有一吨重 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...making it so dense that just a teaspoon of this white dwarf would weigh 1 ton 595 00:59:24,556 --> 00:59:28,227 我们太阳也是这种令人胆寒的下场 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's a chilling premonition of our sun's fate. 596 00:59:28,394 --> 00:59:32,531 60亿年后，太阳会变成一颗白矮星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Six billion years from now, it will become a white dwarf 597 00:59:33,132 --> 00:59:36,869 它的死亡即宣告我们地球生命的终结 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its death will herald the end of life on earth 598 00:59:38,370 --> 00:59:42,007 这让你好奇到底有多少外面的世界像这样存在和消失 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Makes you wonder how many other world have come and gone... 599 00:59:42,174 --> 00:59:47,780 多少未知的宇宙故事永远失落 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...celestial stories left untold, lost forever. 600 00:59:51,383 --> 00:59:55,888 但是它们中最伟大的故事还是要说的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But the greatest story of them all is still to be told 601 00:59:58,857 --> 01:00:02,694 我们必须让时间倒流回到第一章 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We must go back through time to the very first chapter... 602 01:00:02,861 --> 01:00:06,532 讲一件关于宇宙起源的故事 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to learn how the universe began. 603 01:00:10,669 --> 01:00:14,540 散布着死去恒星的残骸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The scattered remains of dead star... 604 01:00:14,907 --> 01:00:17,209 蟹状星云(隶属金牛座) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the Crab Nebula 605 01:00:19,311 --> 01:00:25,284 我们距离地球6000光年 深入到一座星际坟墓 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Six thousand light years from home, deep inside a stellar graveyard 606 01:00:26,251 --> 01:00:27,619 我们已经学到了很多 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We've learnt so much 607 01:00:27,786 --> 01:00:31,657 看到一些本来不可思议的事情 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...seen things we'd never have believed possible 608 01:00:32,624 --> 01:00:37,596 像这样的情景以前是无法想象的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Now, sights like this, wonders once beyond imagination... 609 01:00:37,763 --> 01:00:40,099 现在却是司空见惯了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...we take in our stride 610 01:00:42,734 --> 01:00:45,370 我们准备好了面对前方的一切 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're ready to face whatever lies ahead 611 01:00:45,537 --> 01:00:50,609 决心抵达宇宙的边缘 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Determined to reach the edge of the universe 612 01:00:53,479 --> 01:00:58,117 现在风暴过后的平静 大爆炸后的平静 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is the calm after the storm, after an massive explosion... 613 01:00:58,283 --> 01:01:04,456 超新星把一颗恒星变成一团尘埃和气体 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...a supernova that turned a star into dust and gas 614 01:01:12,631 --> 01:01:14,466 暴风眼 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The eye of the storm. 615 01:01:14,633 --> 01:01:19,404 是一颗旋转脉冲的恒星， 脉冲星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A spinning pulsating star, a pulsar. 616 01:01:23,242 --> 01:01:28,313 重力把巨大恒星的核心挤压成这么小 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The gravity has squeezed the giant star's core down to this 617 01:01:31,450 --> 01:01:36,655 它的直径只有12英里，密度之高无法想象 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's just 12 miles across, unimaginably dense 618 01:01:36,822 --> 01:01:39,825 一个针头大小的物质可能就有几百吨 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}One pinhead of this would weigh hundreds... 619 01:01:39,992 --> 01:01:42,694 甚至几百万吨重 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...maybe millions of tons. 620 01:01:42,861 --> 01:01:46,632 当它收缩时，就像花样滑冰运动员在原地旋转一样 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And as it shrank , like a figure skater spinning on the spot... 621 01:01:46,798 --> 01:01:49,401 展开双臂然后收缩回来 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...arms outstretched , then pulling them in... 622 01:01:49,568 --> 01:01:52,437 它开始越转越快 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it began to spin faster. 623 01:01:55,007 --> 01:02:00,846 两道光、能量和辐射束每秒钟旋转30次 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Two beams of light, energy, radiation, spinning 30 times a second 624 01:02:01,013 --> 01:02:04,650 推动着庞大的尘埃和云团 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Powering the huge cloud of dust and gas 625 01:02:06,685 --> 01:02:12,024 这里的辐射非常多，甚至比太阳的辐射还多 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's so much radiation here, more even than on the Sun. 626 01:02:18,797 --> 01:02:22,968 这是我们到目前为止遭遇到的最致命的东西 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}That was easily the deadliest thing we've encountered so far 627 01:02:28,874 --> 01:02:31,577 若在以前，它必定会让我们惊恐万状 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Once, it would have terrified us 628 01:02:33,478 --> 01:02:35,581 但是现在我们知道 没有危险 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But now we realize that without the dangers... 629 01:02:35,747 --> 01:02:38,116 就不会有奇迹 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...there'd be no wonders 630 01:02:39,551 --> 01:02:43,488 没有梦魇 就没有梦想 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Without the nightmares, there'd be no dreams 631 01:02:55,200 --> 01:02:57,869 现有有一种奇怪的感觉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Getting a strange sensation 632 01:02:59,137 --> 01:03:03,175 似乎这里有某种不祥的东西 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A feeling as though there's something bad out here... 633 01:03:03,609 --> 01:03:06,278 一个不怀好意的家伙 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...a malevolent presence. 634 01:03:06,578 --> 01:03:09,481 这是我们不想遇到的东西 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The one thing we didn't want to encounter 635 01:03:09,648 --> 01:03:15,254 无比的黑暗遮挡了它后面的星星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Impossibly black, blotting out the stars behind it 636 01:03:16,054 --> 01:03:19,625 我们正在凝视的就是灭绝 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We’re staring into the face of extinction... 637 01:03:22,127 --> 01:03:25,230 巨大恒星的残骸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the remains of a giant star... 638 01:03:26,398 --> 01:03:28,500 黑洞 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...a black hole. 639 01:03:33,972 --> 01:03:37,009 它比脉冲星密度高得多 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Far denser than a pulsar... 640 01:03:38,443 --> 01:03:41,179 无法抗拒 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and impossible to resist 641 01:03:46,251 --> 01:03:50,722 它的引力之大连光线也无法逃脱 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Its gravity is so intense, not even light can escape. 642 01:03:59,564 --> 01:04:02,768 这颗小行星就是一块岩石 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This asteroid, it's a lump of solid rock... 643 01:04:02,934 --> 01:04:07,673 但它正在被拉长 被黑洞吸引过去 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...but it's actually stretching, being dragged towards the gaping hole 644 01:04:07,839 --> 01:04:11,343 黑洞内部没有我们已知的物质 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Inside, there's no matter as we know it. 645 01:04:11,510 --> 01:04:17,983 没有时间 没有空间 所有的物理定律在这里都会崩溃 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}No time, no space, all the rules of physics collapse. 646 01:04:27,492 --> 01:04:29,795 那个小行星消失了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The asteroid is gone 647 01:04:30,529 --> 01:04:33,065 没人知道它的下落 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Nobody really know where 648 01:04:33,732 --> 01:04:37,502 这是人类理解力的极限 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is the edge of human understanding 649 01:04:37,669 --> 01:04:41,673 我们的银河系里可能潜伏着数百万个黑洞 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There could be millions of black hole creeping around our galaxy... 650 01:04:41,840 --> 01:04:45,310 更有可能比天空的所有的恒星都多 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...more perhaps than all the stars in the sky... 651 01:04:45,477 --> 01:04:49,748 但是当我们看到黑洞的时候就为时已晚了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...But we wouldn't see them until it was too late. 652 01:04:56,588 --> 01:04:59,958 像这颗恒星 旋转... {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like this star, spiraling... 653 01:05:00,125 --> 01:05:04,262 ...消失在一个隐形的黑洞中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...disappearing, down an invisible sinkhole 654 01:05:05,063 --> 01:05:08,700 谁能说我们不是生活在一个巨大的黑洞中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Who's to say we don't live inside a vast black hole... 655 01:05:08,867 --> 01:05:12,137 整个宇宙说不定也是处于 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...that the whole universe isn't inside one right now... 656 01:05:12,304 --> 01:05:14,239 另一个宇宙的黑洞中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...inside another universe? 657 01:05:14,406 --> 01:05:18,810 这些东西想久了，你会头晕脑胀 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Think about it for too long and your mind reels 658 01:05:20,412 --> 01:05:25,317 有时感觉我们看到的越多，了解的却越少 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Sometimes it feels like the more we see, the less we know. 659 01:05:32,190 --> 01:05:36,261 我们仍在我们的银河系内 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And we're still in our own galaxy, the Milky Way.. 660 01:05:38,663 --> 01:05:43,668 无垠的宇宙还在我们前方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the vastness of the universe beyond still lies ahead 661 01:05:44,870 --> 01:05:51,042 奇迹、危险和秘密都在那里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The wonders, the dangers, the secrets, they're out there... 662 01:05:53,044 --> 01:05:56,348 正等着被探索 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...waiting to be discovered 663 01:06:08,593 --> 01:06:13,098 距离地球7000光年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Seven thousand light years from home 664 01:06:14,232 --> 01:06:17,936 似乎我们置身于树木浓密的森林中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's as though we're in a forest thick with trees. 665 01:06:18,103 --> 01:06:23,074 每棵树都那么美丽、迷人 不可能遥望外面 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Each so beautiful, so fascinating, it's impossible to look beyond 666 01:06:23,241 --> 01:06:26,111 去看到全局 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to see the bigger picture. 667 01:06:26,278 --> 01:06:29,381 我们必须找到出路 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We have to find a way through... 668 01:06:29,548 --> 01:06:33,185 抵达星系边缘的开阔地带 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to reach the clearing at the galaxy's edge 669 01:06:40,559 --> 01:06:44,830 但是面对这样的美景，让人流连忘返(天鹰星云) {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But faced with sights like this, its hard to leave 670 01:06:45,997 --> 01:06:52,070 庞大的发光云团上面矗立着这些巨大的尘埃高塔 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A colossal glowing cloud topped by these great towers of dust 671 01:06:52,237 --> 01:06:54,906 它们是创世之柱 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the Pillars of Creation 672 01:06:55,073 --> 01:06:58,009 犹如进入未知世界的大门 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like a gateway into the unknown. 673 01:06:59,578 --> 01:07:03,982 这是是一个布满胚胎期恒星系统的工厂 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A star factory packed with embryonic star systems... 674 01:07:04,850 --> 01:07:08,420 每一个恒星系都像我们太阳系那么大 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...each larger than our solar system. 675 01:07:18,930 --> 01:07:24,369 我们必须赶紧离开 否则会无法自拔 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}we have to resist its siren song, tear ourselves away... 676 01:07:24,703 --> 01:07:28,173 以便能继续前进到星系的边缘 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to carry on towards the edge of the galaxy 677 01:07:44,389 --> 01:07:49,327 炫于银河的美丽 我们无视它的危险 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Dazzled by the Milk Way's beauty, we've been blinded to its terrors 678 01:07:49,494 --> 01:07:53,498 于是闯进了宇宙雷区 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and strayed into a cosmic minefield 679 01:07:54,866 --> 01:07:57,769 好像是一场慢动作的爆炸场面 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like an explosion in slow motion. 680 01:07:57,936 --> 01:08:02,807 一颗巨大的恒星，亮度是我们太阳的数百万倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A massive star, millions of times brighter than our sun. 681 01:08:03,575 --> 01:08:06,177 它正在崩解 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's going into meltdown 682 01:08:07,679 --> 01:08:09,781 维持它的燃料即将耗尽 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The fuel that sustains it is running out... 683 01:08:09,948 --> 01:08:13,652 给它提供能量的核反应正在逐渐减少 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...the nuclear reactions that power it winding down 684 01:08:13,818 --> 01:08:17,289 我们看到是它的垂死挣扎 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We're watching its death throes 685 01:08:35,807 --> 01:08:40,312 一个更大的 险象环生的不稳定恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}An even bigger, dangerously unstable star 686 01:08:40,478 --> 01:08:43,248 但是这个会爆炸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But this one's about to explode 687 01:08:44,015 --> 01:08:45,650 像这样一个巨大恒星死亡时 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And when a star this big dies... 688 01:08:45,817 --> 01:08:49,955 爆炸比超新星剧烈一百倍 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it's a hundred times more violent than a supernova. 689 01:08:51,022 --> 01:08:55,360 无意中我们撞见了最剧烈的恒星之死 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We've stumbled into the most violent star death of all... 690 01:08:55,527 --> 01:08:57,796 超超新星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...a hypernova. 691 01:09:09,975 --> 01:09:14,546 它的核心坍塌了 正在变成一个黑洞 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The core's collapsed, it's becoming a black hole. 692 01:09:19,084 --> 01:09:22,087 恒星内部汹涌而出的冲击波 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And that's the shock wave, surging through the star... 693 01:09:22,253 --> 01:09:25,757 撕碎恒星外层并抛向太空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...ripping its outer layers into space. 694 01:09:52,350 --> 01:09:55,754 致命的超超新星 冰冻的彗星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Deadly hypernovas, frozen comets... 695 01:09:55,920 --> 01:10:01,826 烧焦的行星 白矮星 红巨星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...scorched planets, white dwarves, red giants 696 01:10:02,927 --> 01:10:07,098 巨大银河水池里的小水滴 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Tiny drops in a vast pool of white light... 697 01:10:08,400 --> 01:10:13,038 我们的星系，银河 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...our home galaxy, the Milky Way 698 01:10:14,973 --> 01:10:17,676 我们想知道我们的位置 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We wanted to know where we fit in 699 01:10:19,177 --> 01:10:21,279 下面就是答案 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Here's our answer. 700 01:10:25,950 --> 01:10:28,953 古往今来的文明 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Civilizations, past and present 701 01:10:29,120 --> 01:10:31,923 每一个古人今人 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Everyone that's ever lived 702 01:10:32,757 --> 01:10:36,061 最小的甲虫 最高的山脉 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The smallest bug, the highest mountain... 703 01:10:36,227 --> 01:10:42,100 全都看不见，甚至算不是一个小斑点 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...all of it invisible, not even a tiny speck. 704 01:10:46,805 --> 01:10:51,943 我们的小地球正在绕着一个毫不起眼的恒星的旋转 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Our home is a minor planet orbiting an insignificant star. 705 01:10:52,110 --> 01:10:56,848 如果它马上消失 也没人会注意 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It is disappeared right now, who would even notice? 706 01:10:59,050 --> 01:11:04,022 但到目前为止我们还没有找到其他我们愿意居住的地方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And yet, so far, we've found nowhere else we would rather live... 707 01:11:04,189 --> 01:11:06,591 也没有能够居住的地方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...nowhere we could live 708 01:11:07,926 --> 01:11:10,328 只有现在远离故乡 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's only now, far from home... 709 01:11:10,495 --> 01:11:14,032 我们才真正开始珍视它 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...that we're beginning to truly appreciate it. 710 01:11:21,072 --> 01:11:26,311 看看这些恒星 数十万颗恒星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Look at all these stars, hundreds of thousands of them 711 01:11:29,080 --> 01:11:35,253 其中一颗，应该不只一颗 一定能够支持生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Surely one of them, more than one, must be capable of supporting life. 712 01:11:58,810 --> 01:12:04,516 也许在这一群恒星组成的大星团里就有 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Maybe here in this swarm of stars, the Great Cluster 713 01:12:05,283 --> 01:12:09,487 1970年代，天文学家向这个方向发出了信息 [译注:即M13 武仙座球状星团] {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Back in the 1970's, astronomers sent a message in this direction 714 01:12:09,654 --> 01:12:14,626 详细描述了人类DNA结构和我们太阳系的位置 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...detailing the structure of our DNA and our solar system's location 715 01:12:15,393 --> 01:12:21,065 至少还要25000年，这些信息才能到达这里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But the message won't arrive here for another 25,000 years. 716 01:12:25,336 --> 01:12:28,339 我们仍然没有发现外星生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We haven't found alien life yet 717 01:12:28,506 --> 01:12:30,975 但同样也没有任何理由去相信宇宙中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But neither have we found any reason to believe... 718 01:12:31,142 --> 01:12:34,779 没有外星生命 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it isn't out there somewhere. 719 01:12:35,213 --> 01:12:36,714 有一个方程式 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There's an equation devised... 720 01:12:36,881 --> 01:12:42,086 是设计用来估算其他发达文明的数量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to estimate the number of other advanced civilizations 721 01:12:42,253 --> 01:12:44,622 计算的结果令人震惊 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The result is startling. 722 01:12:45,223 --> 01:12:50,762 仅在我们银河系可能就有数百万个文明 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There could be millions of civilizations just in our own galaxy. 723 01:13:06,144 --> 01:13:10,181 到目前为止，我们看到一切都在银河内 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Everything we've seen so far is inside the Milk Way 724 01:13:12,917 --> 01:13:18,122 我们准备离开我们的星系 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Now we're ready to leave our home galaxy... 725 01:13:18,289 --> 01:13:21,726 进入星系际空间 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...to enter intergalactic space. 726 01:13:22,227 --> 01:13:27,699 或许我们可以找到机会回答终极问题 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Here's our chance to solve the ultimate mystery... 727 01:13:27,866 --> 01:13:32,737 并有机会去经历创世的一刻 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...and experience the moment of creation. 728 01:13:44,482 --> 01:13:46,451 离开银河 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Beyond the Milk Way... 729 01:13:46,618 --> 01:13:49,821 穿越星系间巨大空间 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...through the vast expanse between galaxies. 730 01:13:49,988 --> 01:13:55,960 排除万难，进入星系际空间 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Against all the odds, we've made it to intergalactic space 731 01:14:05,837 --> 01:14:08,606 这里看不到地平线 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Out here, there's no horizon in sight. 732 01:14:08,773 --> 01:14:14,045 即使最近的星系也远在数十万光年外 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Even the closest galaxies are hundreds of thousands of light years away 733 01:14:15,413 --> 01:14:17,615 被银河系巨大引力 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The remains of galaxies ripped apart... 734 01:14:17,782 --> 01:14:21,719 撕碎的其他星系的残骸 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...By the Milky Way's huge gravitational pull... 735 01:14:21,886 --> 01:14:25,823 散布在空无之中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...scattered among nothing 736 01:14:30,094 --> 01:14:34,699 这是宇宙中最接近完美真空的地方 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This is as close as the universe gets to a perfect vacuum. 737 01:14:34,866 --> 01:14:37,769 但即使这里也不是完全真空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But even this isn't totally empty. 738 01:14:37,936 --> 01:14:43,041 这里有稀薄的气体，微量的尘埃 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}There are thin wisps of gas, tine traces of dust 739 01:14:43,207 --> 01:14:47,412 还有其他的东西 暗物质 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And something else, dark matter 740 01:14:48,546 --> 01:14:50,782 神秘的暗物质 我们无法看见、 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So mysterious, we can't see it... 741 01:14:50,949 --> 01:14:55,853 感觉、品尝、触摸甚至不能测量 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...feel it, taste it, touch it or even measure it. 742 01:14:56,554 --> 01:15:00,291 然而又很普通，它有可能占我们宇宙中所有物质 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Yet so common, it could make up over 90 percent... 743 01:15:00,458 --> 01:15:03,494 十分之九 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...of all the matter in the universe. 744 01:15:03,661 --> 01:15:05,530 如果暗物质的确存在 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}If dark matter does exist.. 745 01:15:05,697 --> 01:15:08,866 那就不存在真空这回事了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it means there's no such thing as empty space. 746 01:15:09,033 --> 01:15:13,438 即使在这里，我们也是被物质包围着 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Even out here, we're surrounded by matter 747 01:15:13,604 --> 01:15:17,775 由于星系间明显的引力我们才认为存在暗物质 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We think it exists because of its apparent hold on galaxies 748 01:15:17,942 --> 01:15:22,580 例如大麦哲伦星云 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Like this one, the Large Magellanic Cloud 749 01:15:27,085 --> 01:15:31,689 它距离银河系16万光年 即使现在最快的太空飞船 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A 6-billion-year journey in today's fastest spacecraft 750 01:15:31,856 --> 01:15:34,926 也要飞行60亿年 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...160 thousand light years from the Milky Way... 751 01:15:35,093 --> 01:15:38,396 它正处于银河系引力的边缘 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...at the edge of its gravitational reach 752 01:15:39,097 --> 01:15:44,002 这个星系应该被卷进太空 但某些东西把它固定在这里 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}This galaxy should spin off into space, but something is holding it here... 753 01:15:44,168 --> 01:15:49,607 某种看不见却强大的东西 是暗物质 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...something invisible, powerful, dark matter 754 01:15:51,976 --> 01:15:57,415 恒星、星团、星云 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Stars, clusters of stars, nebulae... 755 01:15:57,582 --> 01:16:01,019 它是巨大的天文宝库 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it's a vast astronomical treasure trove. 756 01:16:05,823 --> 01:16:10,728 但是你看这个，看起来很想一串闪亮的珍珠 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But look at this, it's like a string of gleaming pearls. 757 01:16:10,895 --> 01:16:12,663 一个火球 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}It's a fireball... 758 01:16:12,830 --> 01:16:16,601 在强烈爆炸后向外扩张 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...expanding out from what must have been a massive explosion. 759 01:16:16,768 --> 01:16:18,903 一颗超新星 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}A supernova. 760 01:16:20,772 --> 01:16:24,976 爆炸产生的光非常亮，当20年前抵达地球时 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}So bright that when light from the explosion reached Earth 20 years ago... 761 01:16:25,143 --> 01:16:28,012 用肉眼就可以看到 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...it was visible to the naked eye 762 01:16:28,646 --> 01:16:31,682 而且爆炸非常强烈，引发了一连串核反应 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}And so violent, it triggered a string of nuclear reactions 763 01:16:31,849 --> 01:16:35,686 迫使原子聚合生成新的元素 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...forcing atoms together, creating new elements... 764 01:16:35,853 --> 01:16:42,527 金、银、白金 被抛入太空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...gold, silver, platinum, blasting them out into space. 765 01:16:47,665 --> 01:16:50,034 你手指上戒指里的黄金 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}The gold in the ring on you finger... 766 01:16:50,201 --> 01:16:53,337 就是数百亿年前在这样一个 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...was forged in a massive supernova like this... 767 01:16:53,504 --> 01:16:57,942 距离数兆英里的超新星内部中生成的 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...trillions of miles away, billions of years ago. 768 01:17:00,178 --> 01:17:04,348 在我们出发前，宇宙似乎与我们无关 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}Before we left home, the universe seemed desperate... 769 01:17:04,515 --> 01:17:08,352 只是存在于我们头顶上的天空 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}...something out there, up in the sky. 770 01:17:09,020 --> 01:17:10,488 但是现在我们更了解了 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}But now we know better. 771 01:17:10,655 --> 01:17:15,593 我们是宇宙，它就在我们之中 {\fscx75\fscy75\1c&H80FFFF&\3c&HFF0000&}We are the universe, and it is within us 772 01:17:22,033 --> 01:17:26,771 在穿越这个深渊之时，这个想法让我们稍感安慰
