Hubble's image of Carina shows a region over 50 light-years across.
哈勃拍攝的船底座星云有50光年寬。
Here too are the EGGs that will one day become stars encircled by planets.
這里也有EGGs，終有一天會演化成行星環繞的恒星。
Among the thousands of newborn stars lurks a surprise.
在數以千計的新生恒星中潛藏著一個意外驚喜。
Within the cloudy halls of Carina, Hubble detects the death throes of a massive star.
在船底座星云云霧遮撓的中心，哈勃探測到一個正在死亡的巨型恒星。
For scientists, a dying star is an opportunity to see the future of our own solar system.
對科學家來說，觀測一個瀕死的恒星是了解我們太陽系的未來的機會。
What these Hubble images show are shells of gas that serve as tombstones.
哈勃圖片顯示氣態外殼像墓碑一樣包裹著瀕死的恒星。
Their quiet beauty is deceptive.
它們的寧靜之美是假象。
These walls of color are the outer layers of a star much like our sun.
這些彩色外殼是恒星的外層，就象我們的太陽一樣。
As a star runs out of fuel, these layers expand, until the gravity of the star can no longer hold them.
當恒星的能量耗盡，它的外層就會開始擴展，直至恒星的重力無法吸引住它們。
Eventually, they are released into space.
最終，它們被釋放至太空中，
In 2004, Hubble captures an image that gives us a glimpse of our eventual demise.
在2004年哈勃捕捉的一張圖片讓我們知道了我們的最終宿命
The Helix Nebula.
旋狀星云。
As these outer layers of a star expand, they leave behind a searing hot ball of solidified oxygen and carbon, astronomers call a "white dwarf".
當一顆恒星的外層擴展后，只留下中心由固體氧和碳構成的炙熱的球體，天文學家稱其為“白矮星”。
Someday, the same thing will happen to our own sun.
早晚有一天，太陽也會發生同樣的事。
The sun will run out of fuel and that will cause it to expand into a giant red star.
太陽也會耗盡能量，然后太陽擴展成為一顆“紅巨星”。
That's bad news for our world.
那對我們來說可真是個壞消息。
The temperature on the surface of our planet will rise over a thousand degrees.
到時地球表面的溫度會超過1000度，
All life on earth will perish.
地球上所有的生命都會滅亡。
A wall of hot gas will sweep over the earth, through our solar system, and into space.
炙熱的氣體會在席卷整個地球、整個太陽系后進入太空。
Every planet and moon in its path will be incinerated.
在其擴展路徑上的所有行星和衛星都會被烤焦。
The only thing left of our Sun will be a splash of color visible from thousands of light-years away.
太陽能留下的唯一印記，將會在數千光年以外的地方被看到。
Like this.
就像這樣。
So the human race has its warning.
人類由此得到了警示。
We have 5 billion years to clear out of town.
我們還有50億年的時間來逃離太陽系。
But even the death of our own sun hardly compares to a more powerful downfall.
不過太陽死亡的可怕還無法與一些更大質量的恒星相比。
Some stars are over a hundred times more massive than our sun.
一些恒星的質量要比太陽大幾百倍。
The bigger the star, the shorter its life, and the more violent its death.
恒星質量越大，壽命越短，死亡時的變化也更狂暴。
