?Our world. warm, comfortable, familiar...
我们的世界 温暖、舒适 熟悉
...But when we look up, we wonder:
但当我们仰望天空 我们想知道
Do we occupy a special place in the cosmos?
我们是居住在宇宙中一个独特的地方
Or are we merely a celestial footnote
或仅仅是太空的小小一隅?
Is the universe welcoming or hostile?
宇宙是友善的还是充满敌意？

我们是一直站在这里猜想
We could stand here forever, wondering
还是离开故园来一次终极探险
Or we could leave home on the ultimate adventure
去发现奇观
To discover wonders
直面恐怖
Confront horrors
美丽的新世界
Beautiful new worlds
邪恶的黑暗势力
Malevolent dark forces
时间的起点
The Beginning of time.
创世的时刻
The moment of creation.
我们是否有坚持到底的勇气
Would we have the courage to see it through?
或是逃回家？
Or would we run for home?
想找到答案只有一个方法
There's only one way to find out
我们开始一步步时空之旅
Our journey through time and space begins with a single step.
离地面60英里（100公里）高度,就是太空边缘...
At the edge of space, only 60 miles up...
仅仅一个小时车程
...just an hour's drive from home
地面上，生活在继续
Down there, life continues.
车水马龙 商业繁忙
The traffic is awful, stocks go on trading
《星际迷航》还在播出
...and Star Trek is still showing
当我们回到家 如果我们还能回家
When we return home, if we return home...
一切还会如初吗？
...will it be the same?
我们还是原来的我们吗？
Will we be the same?
我们必须抛掉这一切
We have to leave all this behind
步入前方广阔的黑暗海洋
To dip out toes into the vast dark ocean
前往月球
On to the Moon.
在我们之前，已有数十名宇航员前往月球
Dozens of astronauts have come this way before us
其中12人踏上了月球
Twelve walked on the moon itself
月球距离地球只有25万英里（40万公里）
Just a quarter of a million miles from home.
坐宇宙飞船需要3天
Three days by spacecraft
贫瘠
Barren.
荒芜
Desolate.
月球看起来就像一个遗弃的战场
It's like a deserted battlefield
但是惊人的熟悉
But oddly familiar.
那么近，就像我们几乎没有离开家
So close, we've barely left home
尼尔·阿姆斯特朗的第一个脚印
Neil Armstrong's first footprints.
看起来就像在昨天留下的
Looks like they were made yesterday
那里没有能够改变脚印的空气
There's no air to change them.
这些足迹会存在数百万年
They could survive for millions of years
或许比人类存在的时间都长
Maybe longer than us.
我们的时间是有限的
Our time is limited
我们必须自己踏出自己的一大步
We need to take our own giant leap
1百万英里 5百万英里 2千万英里
One million miles, 5 million, 20 million miles.
远

征前人未曾到达的地方
We're far beyond where any human has ever ventured
一个友善的面孔从黑暗中浮现
Out of the darkness, a friendly face
爱之女神 金星
The goddess of love, Venus.
启明星
The morning star.
长庚星
The evening star.
它可以在东方迎接新的一天...
She can welcome the new day in the east...
还会在西方道晚安
...say good night in the west
金星是地球的姊妹星...
A sister to our planet...
...大小和引力与地球相仿
...she's about the same size and gravity as Earth.
我们在这里应该是安全的
We should be safe here
但是金星快车空间探测器却时刻提醒着我们
But the Venus Express space probe is setting off alarms
告诉我们那些耀眼的云层是由致命的硫酸构成
It's telling us, these dazzling clouds, they're made of deadly sulfuric acid
金星的大气层充斥着二氧化碳
The atmosphere is choking with carbon dioxide
没想到金星是一个愤怒的女神
Never expected this Venus is one angry goddess.
有毒的空气 难以忍受的压力
The air is noxious, the pressure unbearable.
还有炙热 温度接近900度（500°C）
And it's hot, approaching 900 degrees
多呆一会 我们会被腐蚀、窒息、压碎和烤焦
Stick around and we'd be corroded suffocated, crushed and baked
任何东西都无法在这里生存
Nothing can survive here.
即使像前苏联金星号机器人探测器
Not even this Soviet robotic probe.
它的厚重装甲已被这极端的大气环境给毁了
Its heavy armor's been trashed by the extreme atmosphere.
从地球看她是多么可爱 近观这个女神却是可怕的
So lovely from Earth, up close, this goddess is hideous
她是来自地狱的姊妹
She's the sister from hell.
数千座火山犹如长满了痘疮
Pockmarked by thousands of volcanoes
大气层中的二氧化碳留住了太阳热量
All that carbon dioxide is trapping the Sun's heat.
金星正在燃烧
Venus is burning up.
这是无节制的全球气候变暖
It's global warming gone wild
在它变暖之前或许是美丽而平静的
Before it took hold, maybe Venus was beautiful, calm...
...很像她的姊妹星 地球
...more like her sister planet, Earth.
也许就它是我们地球的未来
So this could be Earth's future
那些闪烁的星星哪里去了？
Where are the twinkling stars?
美丽的圆球滑进了太空？
The beautiful spheres gliding through space?
或许我们不应该来这里 我们应该回去
Maybe we shouldn't be out here, maybe we should turn back
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）
But there's something about the Sun, something hypnotic, like the Medusa
可怕的让人无法正视，也无法抗拒她的力量
Too terrible to look at, too powerful to resist
引诱我们继续前进 像飞蛾扑火
Luring us onward on, like a moth to a flame.
等等，这里还有其他东西被太阳

炙烤
Wait ,there's something else, obscured by the sun
它一定是水星
It must be Mercury.
太靠近太阳，就会这样
Get too close to the sun, this is what happens.
这里温度剧烈变化
Temperatures swing wildly here
晚上会到零下275度（-170°C）
At night, it's minus 275 degrees
...正午则超过800度（400°C）
e midday, it's 800 plus.
烧焦再被冰冻
Burnt then frozen.
信使号空间探测器发现了一些奇怪的现象
The MESSENGER space probe is telling us something strange.
相对体积来说，小小的水星具有强大的引力
For its size, Mercury has a powerful gravitational pull.
它就像一个裹着薄薄岩石层的大铁球
It's a huge ball of iron, covered with a thin veneer of rock
这是一颗大行星留下的核心
The core of what was once a much larger planet.
其他部分去哪里了呢？
So where's the rest of it?
或许是一个迷路的行星猛地撞进了水星
Maybe a stray planet slammed into Mercury
...在一场致命的宇宙弹球游戏中水星的外层被炸掉了
...blasting away its outer layers in a deadly game of cosmic pinball
这些游荡的行星在宇宙中疯狂地掠过
Whole worlds on the loose careening wildly across the cosmos...
...毁掉他们道路上的一切
...destroying anything in their path
我们就在其中
And we're in the middle of it
脆弱、裸露而且渺小
Vulnerable, exposed, small
这一且都在告诉我们该回去了
Everything is telling us to turn back.
但是谁又能抗拒的了
But who could defy this?
散发着迷人光彩的太阳？
The Sun in all its mesmerizing splendor
我们的光线，我们的生命
Our light, our lives...
我们的一切都被太阳控制着
...everything we do is controlled by the Sun
依赖于它
Depends on it
它是驾着战车穿越天际的希腊美男子太阳神
It's the Greek god Helios driving his chariot across the sky
是每天重生的埃及神“拉”（埃及神话里的太阳神）
The Egyptian god Ra reborn every day
以及巨石阵夏至的日出
The summer solstice sun rising at Stonehenge.
数百万年来
For millions of years...
我们对太阳神的景仰止于远观
...this was as close as it got to staring into the face of God
由于实在太远
It's so far away...
如果太阳熄灭了，8分钟后我们才会知道
...it is burned out, we wouldn't know about it for eight minutes
太阳大到可以装下100万颗地球
It's so Big, you could fit one million Earths inside it
谁需要这些数字呢 我们看到了它的真面目
But who needs number? we've got the real thing
我们每天看到太阳挂在天空的熟悉面孔
We see it every day, a familiar face in our sky
现在近观它，又陌生起来
Now, up close, it's unrecognizable.
由炙热气体形成的汹涌大海
A turbulent sea of incandescent gas
表面温度超过1万度（5000°C）
The thermometer pushes 10,000 degrees
难以置信的是

它的核心温度则可以到数千万度
can't imagine how hot the core is ,could be tens of millions of degrees
这里热到足以能够
Hot enough to transform millions of tons of matter
每秒钟把数百万吨物质转化成能量
...into energy every second
超过人类有史以来产生的所有能量
More than all the energy ever made by mankind
地球上所有的核武器对于它都是小巫见大巫
Dwarfing the power of all the nuclear weapons on Earth.
在地球，这些能量是我们利用的光和热
Back home, we use this energy for light and heat
近距离观看时，却是令人感到不安
But up close, there's nothing comforting about the Sun.
太阳的电磁活动迸发出巨大的炙热气体环状物（日珥）
Its electrical and magnetic forces erupt in giant molten gas loops.
有的足有一打地球那么大
Some are larger than a dozen Earths
释放的能量超过一千万个火山
More powerful than 10 million volcanoes.
当它喷发的时候 就会露出下面温度较低的部分
And when they burst through they expose cooler layers below...
形成太阳黑子
...making sunspots.
太阳黑子比周围温度低一些 所以看起来是黑的
A fraction cooler than their surrounding, sunspots look black...
但仍比地球任何东西都热
...But they're hotter than anything on Earth.
太阳黑子同样巨大，超过地球大小的20倍
And massive up to 20 times the size of Earth.
但是总有一天，这一切都会结束
But one day, all this will stop
太阳的燃料会耗尽
The Sun's fuel will be spent.
太阳死去，地球也会随之死亡
And when it dies, the Earth will follow
这个神祇创造了生命，也会摧毁生命
This god creates life, destroys it...
要求我们保持距离
...and demands we keep out distance
这个彗星太靠近太阳了
This comet strayed too close
它被太阳的热量蒸发
The Sun's heat is boiling it away...
产生绵延数百万英里的彗尾
...creating a tail that stretches for millions of miles.
这里冰冷彻骨
It's freezing in here.
我们清楚彗星来自哪里 它来自深太空的冰冻垃圾
There's no doubt where this comet's from, the icy wastes of deep space
但你看这些蒸汽、间歇泉和尘埃
But all this steam and geysers and dust...
这是太阳正在融化彗星的冰冻核心
...it's the Sun again, melting the comet's frozen heart.
太奇异了
Strange.
犹如外面包裹着肮脏沥青的巨大脏雪球
A kind of vast, dirty snowball, covered in grimy tar
看起来像是有机物的小颗粒
Tiny grains of what looks like organic material...
被冷冻保存 谁会知道已经保存了多久
...preserved on ice, since who knows when...
也许和太阳系同龄
...maybe even the beginning of the solar system.
如果像这样一颗彗星在数十亿年前撞到年轻的地球
Say a comet like this crashed into the young Earth billions of years ago.
也许带来了生命原始

物质...
Maybe it delivered organic material and water
...有机物和水
...the raw ingredients of life
彗星甚至可能在地球上播下生命之种
It may even have sown the seeds of life on Earth...
后来进化成你和我
...that evolved into you and me
如果彗星现在撞上地球
But say it crashed into the Earth now
想想恐龙吧 被彗星或是小行星的撞击彻底灭绝
Think of the dinosaurs, wiped out by a comet or asteroid strike
这只是时间问题
It's only a question of time.
毫无疑问，总有一天我们会步恐龙的后尘
Eventually, one day, we'll go the way of the dinosaurs
如果地球上的生命灭绝了 我们会被困在这里
If life on Earth was wiped out, we'd be stuck out here...
无家可归，漂泊在危险宇宙中
...homeless, adrift in a hostile universe
我们需要找一个新家
We'd need to find another home
在几百万甚至数十亿的行星中
Among the millions, billions of planets...
一定会有一个行星不会很热，也不会很冷 有空气、阳光和水
...there must be one that's not too hot, not too cold, with air, sunlight, water...
可以让我们舒适居住,生活
...where, like Goldilocks, we could comfortably live
红色行星
The red planet
我们都熟知的火星
Unmistakably Mars.
几个世纪以来，我们一直都在寻找火星上的同伴
For centuries, we've looked to Mars for company...
寻找生命迹象
...for signs of life
那里有外星生物吗？
Could there be extraterrestrial life here?
我们准备好改写史书，撕毁科学书籍
Are we ready to rewrite the history books, to tear up the science books...
颠覆我们的世界了吗？
...to turn our world upside down?
接下来发生的可能会改变一切
What happens next could change everything
火星比任何其他行星都能激发我们的遐想
Mars is the planet that most captures our imagination.
想到科幻电影、漫画，你会联想到什么-
Think of B-movies, sci-fi comics, what follows?
火星人？
Martians?
这都是虚构的，对吗？
It's all just fiction, right?
但如果这里真的有生物呢？
But what it there really is something here?
无法想像，近观火星是一个死去的行星
Hard to imagine, though. Up close, this is a dead planet
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
The activity that makes the Earth livable shut down millions of years ago here
红色、死寂
Red and dead
火星是一块巨大的化石
Mars is a giant fossil.
等一下，还有东西在活动
Wait. Something is alive
一个巨大的尘暴
A dust devil, a big one
绝对超过地球上最大的龙卷风
Bigger than the biggest twisters back home.
这里有风
There's wind here
有风说明有空气
And where there's wind, there's air
可以维持外星生物的空气
Could that air sustain extraterrestrial life?
但对我们的呼吸来说，火星的空气太稀薄了
It's

too thin tor us to breathe.
而且这里没有臭氧层
And there's no ozone layer
没有什么能够保护其不受太阳紫外线的伤害
Nothing to protect us against the Sun's ultraviolet rays.
这里有水
There is water...
但在彻骨的严寒中只能永远被冰冻
...But frigid temperatures keep it in a constant deep freeze
很难相信有什么可以在这里生存
It's hard to believe anything could live here
但是在地球 极冷和极热的地方都有生物存在
Back on Earth, there are creatures that survive in extreme cold, heat...
即使在最深的海沟
...even in the deepest ocean trenches
生命好像病毒
It's as though life is a virus.
会适应环境、会散播
It adapts, spreads
也许我们现在正在携带着
Maybe that's what we're doing right now...
生命的病毒穿越宇宙
...carrying the virus of life across the universe.
即使在最极端的环境里，生命都会找到生存的办法
Even in the most extreme conditions life usually finds a way.
但在这个死去的行星上
But on a dead planet?
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
With no way to replenish its soil, no heat to melt its frozen water?
还有大量尘埃，让我们无法辨别方位
All this dust, it's hard to see where we're going
奥林匹斯山，以希腊众神的家乡命名
Olympus Mons, named after the home of the Greek gods
一座巨大的古火山
A vast ancient volcano.
超过珠穆朗玛峰的三倍高。
Three times higher than Everest.
没有活动的迹象
There's no sign of activity.
自1970年代发现它时就宣告它是一座死火山
Since its discovery in the 1970s, it's been declared extinct
等等
Hang on.
好像是熔岩流
These look like lava flows.
但是任何熔岩流早就该静止了，在陨石撞击下都会被毁灭
But any sign of lava should be long gone. obliterated by meteorite craters
除非这个怪物没有死，只是休眠了
Unless, this monster isn't dead, just sleeping
火星的坚硬地表下可能有岩浆
There could be magma flowing beneath the crust right now...
积累着，等待喷发的一刻
...building up, waiting to be unleashed
火山活动会融化土壤里的冰冻水
Volcanic activity could be melting frozen water in the soil...
将气体充入大气中 循环利用矿物质和养分，
...pumping gases into the atmosphere, recycling minerals and nutrients
创造出适合生命生存的环境
Creating all the conditions needed for life
这让美国大峡谷看起来像是人行道上一条裂缝
This makes the Grand canyon look like a crack in the sidewalk
无尽的荒凉
Endless desolation...
长度足以横跨北美洲
...so vast it would stretch all the way across North America.
但是这里有活动的迹象：侵蚀 看起来像干涸的河床
But here, signs of activity, erosion, and what looks like dried up river beds
也许是火山活动融化了土壤中的冰

Maybe volcanic activity melted ice in the soil...
形成洪水冲出巨大峡谷
...sending water gushing through this canyon.
可能地下火山仍在融冰成水
Underground volcanoes could still be melting ice, creating water
哪里有水，那里就可能会有生命
And where there's water, there could be life
搜寻生命的前锋就是这个简陋的家伙
The hunt for life is spearheaded by this humble fellow...
美国宇航局的机遇号火星漫游车
...the NASA rover, Opportunity.
它找到的证据证明这些贫瘠的平原
It's finding evidence that these barren plains...
曾是古代湖泊或海洋 这些有水的地方可能会藏匿着生命
...were once ancient lakes or oceans that could have harbored life
看看这些山沟
Look at those gullies.
火星轨道探测器总能发现一些新的山沟
Probes orbiting Mars keep spotting new ones.
这进一步证明火星仍活蹦乱跳
More proof that Mars is alive and kicking
也许是火星地表之下的水正在流淌
...that water is flowing beneath its surface right now
水可能维持火星上的生命
Water that could be sustaining Martian life
现在我们要做的就是找到这些生命
Now, all we have to do is find it
或许我们已经找到了，不是在火星，而是在地球
Maybe we've already found what we're looking for on Earth
有人认为生命起源于火星，后来迁移到地球
Some think that life started here and then migrated to Earth
可能是一颗小行星撞击火星
An asteroid impact could've blasted fragments of Mars...
使得包含微生物的火星碎片飞向太空
plete with tiny microbes out into space...
进入年轻的地球 在地球上播种下生命的种子
...and onto the young Earth where they sowed the seeds of life
难怪我们觉得火星那么迷人 它可能就是我们祖先的家园
No wonder we find Mars fascinating, this could be our ancestral home
我们可能都是火星人
It could be we are all Martians
我们熟知的火星远去了
The Mars we thought we knew is gone...
取而代之是这个活跃变化的新行星
...replaced by this new, active, changing planet.
如果我们连我们的隔壁邻居火星都不了解,
And if we don't know Mars, our next door neighbor...
我们怎么能想像前方的惊奇?
...how can we even imagine what surprises lie ahead
我们的方向指向宇宙
Our compass points across the cosmos...
回到140亿年前
...back in time 14 billion years...
创世的那一刻
...to the moment of creation.
此情此景开始让人害怕
This is getting scary.
就像置身于一个巨大的视频游戏
It's like being inside a giant video game
但这些也是真实的
But these are all too real.
小行星，其中有些有数百英里宽
Asteroids, some of them hundreds of miles wide
这个约有20英里长
This one must be about 20 miles long.
你看，上面有个空间探测器
And there, perched on it, a space probe.

降落在一个时速达5万英里
Can't have been easy...
的小行星上可不是件容易的事
...parking on an asteroid traveling at 50,000 miles an hour.
我们一直在努力研究这些碎石
It's a lot of effort just to investigate some rubble.
碎石之间经常碰撞
Rubble that regularly collides...
碎片后来落在地球上，就形成了地球上看到的陨石
...breaks up and rains down on Earth as meteorites.
我们的古人把流星雨看做是魔法的征兆
Our ancestors saw shooting stars as magical omens.
他们是对的
And they were right
就是这样一些碎石聚在一起就会形成行星
Rubble like this came together to make the planets...
包括我们的地球
...including our own
多美的魔法
Pretty magical.
通过测定地球上发现的陨石年龄
By dating the meteorites found on Earth
我们知道行星诞生于45亿年前
...we can tell the planets were born 4.6 billion years ago.
这些殒石是我们太阳系的出生证明
These are the birth certificates of our solar system.
但有些原因导致这些岩石没有形成行星
For some reason, these rocks didn't form into a planet
一定是什么阻止了他们
Something must have stopped them
某种强大的力量
Something powerful.
木星
Jupiter.
犹如巨大的怪物
What a monster
至少比地球的大1000倍
At least a thousand time bigger than Earth...
大到可以装下太阳系其它所有行星
...so vast you could fit all the other planets inside it
木星的巨大体积对它周围产生很大的影响
Something this massive dominates its neighbors
它的引力正在把这些小行星形成扯开
Its gravity is pulling the asteroids apart
真是美极了
And it's breathtaking
但这个美人是个巨兽
But this beauty is a beast.
木星几乎都是由气体构成的
It's almost all gas.
如果在这里着陆，我们会径直穿过它的外层一去不复返
Land here and we'd sink straight through its layers into oblivion.
木星的美丽面孔是
And Jupiter's good looks?
它极端狂暴的产物
The product of ferocious violence
木星自转极快
It's spinning at an incredible rate
卷起时速数百英里的飓风
...whipping up winds to hundreds of miles an hour...
把云层扭曲成条状和大大小小的漩涡
...contorting the clouds into stripes eddies, whirlpools...
这就是传说中的大红斑
...and this, the legendary Great Red Spot
它是太阳系中最大、最猛烈的风暴
The biggest, most violent storm in the solar system.
至少有地球的3倍大 已经肆虐了超过300年了
At least three times the size of Earth, it's been raging for over 300 years
这些翻腾的云产生闪电雷暴
All these churning clouds must have sparked an electrical storm
任何一个闪电都比我们地球上的强一万倍
Just one bolt is 10,000 times more intense than any at home.
远观眺望才是最好最安全的
Looks like the safest place to see Jupi

ter is from a distance
在它的两极
Up there at the poles...
那些光就像我们地球的极光一样在翩翩起舞
...those dancing lights, they're like the auroras back home.
但盖格计数器的读数开始发狂
But the Geiger counter is going wild
致命辐射产生的光看起来也是能致人死地
Even these are deadly, generated by lethal radiation
太空中凡事不可貌相
Out here, nothing is what it seems.
宇宙充满了恐怖和陷阱
The universe is full of terrors, traps.
也许这个五彩缤纷的木卫一是一个避风港
Maybe this is a safe haven, the multi-colored moon, Io
错了
Wrong
大错特错
Very wrong.
那些闪亮的颜色是融岩、火山喷出的岩浆
Those brilliant colors are molten rock, volcanoes spewing lava.
我们神奇的宇宙之旅开始变成了生存之战
Our journey across the universe is turning into a struggle for survival
我们曾希望只要战胜这些危险
We've got to hope that if we outlast the dangers...
我们就会看到无法想像的奇观
...we'll be rewarded by wonders beyond imagination
离开地球4亿英里
Four hundred million miles from Earth...
搭乘民航航班要飞一个世纪
...flying a commercial airliner here would take nearly a century
多么古怪的地方
What a weird looking place...
不可思议的是，它看起来又是那么熟悉
...and yet, strangely familiar
所有的冰、山脊和裂缝 都与北极有点相似
A bit like the Arctic, with all that ice, all those ridges and cracks
它是木星的卫星 木卫二
It's Jupiter's moon, Europa.
也许真的很像北极 冰块漂浮在液态水上
And maybe, like the Arctic, this ice is floating on water, liquid water
但是这里距离太阳有5亿英里
But we're half a billion miles from the Sun.
当然，木卫二是冰冻固体
Surely, Europa is frozen solid
除非木星的引力在它内部造成摩擦
Unless, Jupiter's gravity is creating friction deep inside...
使冰融化，允许生命在它的
...heating the ice into water, allowing life to develop in the water...
冰冻外壳下的水中发展
...beneath its frozen crust.
我们距离外星生物也许只有几英尺远
We might be feet away from aliens
下面有微生物、甲克类，甚至有乌贼构成的生态系统
From a whole ecosystem of microbes, crustaceans, maybe even squid
我们和这些可能存在的外星生物之间
The only thing between us and the possibility of alien life...
只隔着一层薄薄的冰
...this layer of ice.
在我们派出飞船钻透它的冰层之前
But until we send a spacecraft to drill here...
木卫二仍会一直保守它的秘密
...Europa's secrets will remain beyond reach
它挑逗着我们的想像 萦绕在我们梦中
It's captivated our imaginations, haunted our dreams
现在它就在我们面前自转
And here it is, spinning before our eyes
土星
Saturn.
由古罗马农神的名字命名
Named for the Roman god..

.
他曾统治过一个祥和安宁的黄金时代
...who reigned over an golden age of peace and harmony
这个行星是一个巨大的气体球 轻到可以漂浮在水面上
This planet's a giant ball of gas, so light it would float on water
壮观的土星环展开的长度几乎等于地球到月球的距离
Its spectacular rings would stretch almost from Earth to the Moon.
那是卡西尼探测器
There's the Cassini orbiter
它收到鬼魅般的无线电信号
It's picking up ghostly radio emissions
可能是由土星两极的极光产生的
Probably generated by auroras around Saturn's poles
这是真正的天体音乐
This is the real music of the spheres.
卡西尼告诉我们这些土星环的来历
Cassini's telling us where these rings came from.
它们是被土星引力撕碎的卫星残骸
They're the remnants of a moon shattered by Saturn's gravitational pull
彻底毁灭产生的无比美景
Incomparable beauty from total destruction
无数的碎坚冰
Billions of shards of ice
有些很小，就像冰块，有些则有房子那么大
Some as small as ice cubes, others the size of houses.
他们碰撞、破碎、重新聚集
They collide, break apart, reassemble
就是我们太阳系的早期快照
It's like a snapshot of our early solar system...
尘埃和气体环绕着初生的太阳
...as dust and gas orbited the newly born Sun
然后引力施展魔力 吸引碎块聚在一起
...and gravity worked this magic pulling the lumps together...
直到这些碎块形成地球
...until from space trash like this, our home emerged
我们可以一直呆在这里
We could stay here forever
但我们还要赶路，还有很多东西要看
But there's so much further to go, so much more to see.
土卫六 被厚云笼罩着
Like this moon wrapped in thick clouds, Titan.
它有大气层
There's an atmosphere down here
有风、雨，甚至有季节
There's wind, rain ,even seasons
有河流、湖泊和海洋
Rivers, lakes and oceans
看起来和地球很像
It looks so familiar, so similar to Earth.
但那不是水，是液态天然气
But that's not water, it's liquid natural gas
这里天然气比我们地球的油气储量多几百倍
Hundreds of times more natural gas than all the Earth's oil and gas reserves
或许有一天 我们把它当做一个燃料基地
Maybe, one day, we'll use this energy to fuel a colony.
假设土卫六上早已没有生命
Assuming there isn't life here already
惠更斯号探测器在这里寻找答案
The Huygens space probe is here to find out
它报告说土卫六的土壤中存在有机成分
It's telling us there's organic material in the soil.
但这儿太冷了，低到零下300度(华氏)
But it's so cold, minus 300 degrees
生命无法发展
There's no way life could develop
除非土卫六变暖
Unless Titan warms up.
有人预言太阳会变得越来越热
The Sun is supposed to get hotter
真是这样，也许这里会出现

生命
