Eventually, it will become so hot that it triggers nuclear fusion.
最終，越來越高的溫度觸發(fā)了核子反應(yīng)。
And, a star is born.
就這樣，一顆恒星就誕生了。
Heat and radiation from the nuclear fusion generates a stellar wind, sweeping away most of the loose matter in the disc.
核反應(yīng)發(fā)出的熱和輻射引發(fā)了恒星，風(fēng)將“原星碟”中的大部分松散物質(zhì)吹走。
But some of this loose matter remains in orbit around the newborn star.
但是有些松散物質(zhì)卻依然停留在新生恒星的周邊軌道上。
Over time, the debris gathers into more knots and clumps, growing and evolving, into a planet.
隨著時(shí)間推移，這些殘留物結(jié)合在一起形成一些團(tuán)狀物成長并演化成行星。
It really is the case that if you could go back 4.5 billion years ago, and look at the formation of the sun and the solar system,
如果你回到45億年前，觀看太陽和太陽系的形成，
that it would be that kind of an environment that you would find us in.
你將看到和上述情形一樣的狀態(tài)。
Hubble has shown us the genesis of a new solar system and answered an age-old question of how our own star, the Sun, and our Earth, came into existence.
哈勃向我們展示了一個(gè)新的星系的起源過程，回答了我們一個(gè)古老的問題：我們的星球——太陽、地球是如何形成的。
Beyond the Eagle and Orion Nebulae, even larger star forming regions lie within the plane of the Milky Way.
除了老鷹和獵戶座星云，銀河里存在更大的恒星生成區(qū)域。
Scientists wonder if the life cycle of stars is the same in these distant regions.
科學(xué)家們猜想在這些遙遠(yuǎn)的區(qū)域，恒星生命過程是否也是一樣的。
In March 2005, Hubble began relaying images of a new target.
2005年3月，哈勃開始傳送一個(gè)新區(qū)域的圖片。
The Carina Nebula, one of the largest star-forming regions in the sky.
船底星云，宇宙中最大的恒星形成區(qū)域之一。
But the raw data sent by Hubble looks nothing like this.
但是哈勃傳送回來的原始圖像數(shù)據(jù)卻不是我們現(xiàn)在看到的這樣。
Creating images that help scientists unlock the mysteries with this data, falls to imaging expert, Zolt Levay.
圖片處理技術(shù)幫助科學(xué)家們解決了原始數(shù)據(jù)的問題，幫助來自于圖像專家——佐特?李維。
I have emotional attachment to that image not only because of its aesthetic value, but because of the amount of time I spent on it.
我對(duì)這幅圖像懷有深厚的感情，不僅僅因?yàn)樗缹W(xué)上的價(jià)值，還因?yàn)槲以谒厦婊ㄙM(fèi)了大量時(shí)間。
Picture data comes in from Hubble in black and white.
哈勃傳送來的圖像數(shù)據(jù)是黑白的。
Levay assigns colors to these images according to the chemical elements detected by Hubble's instruments.
根據(jù)哈勃上的器械探測到的化學(xué)元素成分，李維給圖片配上了顏色。
Blue shows oxygen.
藍(lán)色代表氧，
Red shows sulphur.
紅色代表硫磺，
And green is hydrogen.
綠色代表氫。
Levay works for about a year to produce the full mosaic out of 48 separate pictures.
處理圖片大概花了李維一年時(shí)間，做出的圖片由48塊區(qū)域拼湊而成。
