Are we alone?And it ties into all the big questions: how do we get here? where are we going?Are we a part of a bigger picture?
我們是否孤單這個問題又涉及到其他大的疑問,比如我們來自何方，又要去到哪里?我們是不是一幅更大畫面的一部分?
But for the longest time ,the question was taboo to science.
但很長一段時間，這個問題卻是科學(xué)研究的禁忌。
Before the Mid-1990s ,it was considered somewhat embarassing to even address the question, because looking for alien life seems a little frighteningly close to science fiction.
在20世紀(jì)90年代中期前，即使是談?wù)撨@類問題都被認(rèn)為是很難堪的，因為尋找外星生命聽起來很嚇人好像科幻一樣。
For decades ,the farthest we got in looking for aliens was imagining them on the silver screen.(What is your name?) After all,alien life needs a hull, and we havn't even find a planet outside our own solar system.
幾十年以來，我們在探索外星生命之上，最多就是在銀屏上想象他們的樣子，你叫什么名字？畢竟外星生命需要一個家，而我們還未在太陽系外找到一個行星。
Scientists in fact never talked about planets around other stars. There is no way to detect them.
科學(xué)家們實際上從不談?wù)搰@其他恒星的行星，因為沒辦法偵測到它們。
And so it was one of those domains of science that you couldn't answer and therefore you didn't talk about it.
所以這是一個我們回答不了的科學(xué)領(lǐng)域，以致于我們就不會去談?wù)撍恕?/div>
Then in 1995, a stronomer discovered a planet orbiting a star 50 light-years from earth. And since then they found hundreds more.
在1995年，一個天文學(xué)家發(fā)現(xiàn)了一個距離地球55光年圍繞恒星運轉(zhuǎn)的行星，從那之后，天文學(xué)家們又發(fā)現(xiàn)了數(shù)百個。
For the first time, in human history ,we realized that our sun with its 8 major planets that go around，it is just one type of a planetary system ,one example of billlions.
這是人類歷史上首次我們發(fā)現(xiàn)我們的有8個主行星圍繞的太陽只是幾百萬個行星系統(tǒng)中的一種形式。
These discoveries are exciting ,but don't expect to dial up ET on these planets anytime soon.
這些發(fā)現(xiàn)著實令人興奮，但別對很快就會發(fā)現(xiàn)外星人抱太大希望。
Well ,it's been a spectacular ride in the last decade to find these planets,most of them are giant planets.
過去幾十年對行星的尋找真的是很驚人，他們多數(shù)都是大行星。
Most of the worlds we found are gas giants which probably couldn't support life.
我們大多找到的是不太有可能支持生命的巨大的氣體星球。
You can't stand on pneumas ,no hard surface,they are large balls of hydrogen and helium gas like Jupiter and Saturn.
你不能站在那些星球上，因為那里沒有堅固的地面，它們都是由氫氣，氦氣等組成的大氣球，比如木星和土星就是這樣。
We have found a few rocky planets with hard surfaces ,but they are many times more massive than earth,and contain the most hostile environments you could ever imagine.
我們雖然找到了一些有地面的巖石行星，但它們比地球大很多倍，并且上面的條件惡劣到你無法想象。
One such planet, CoRoT-7b,orbits so close to its star that surface temperatures reach as high as 3000 degrees.Sunlights here does not bring the sound of birds' song,instead it's an Armageddon of volcanic explosions.
例如CoRoT-7b，它與自己的太陽如此之近以致星球表面溫度高達炙熱的華氏3000度，這里的陽光帶來的不是優(yōu)美的鳥鳴，而是巨大的火山爆發(fā)。
