Ed Weiler celebrates Hubble’s 20th Anniversary

EarthSky

Ed Weiler: The Hubble has discovered things that we could never have anticipated. That is, it’s literally changed our view of the universe.

愛德華?威勒：哈勃望遠(yuǎn)鏡帶來的新發(fā)現(xiàn)是我們未曾想過的。它給我們帶來了觀測(cè)宇宙的全新視角。

You’re listening to NASA astrophysicist Edward Weiler, chief scientist for the Hubble Space Telescope from 1979 to 1998. April 2010 marks its 20th anniversary of launch.

您正在收聽到的是美國國家航空航天局天體物理學(xué)家愛德華?威勒的講話。威勒于1979~1998年間擔(dān)任哈勃空間望遠(yuǎn)鏡首席科學(xué)家。到今年4月，哈勃望遠(yuǎn)鏡已發(fā)射升空20年。

Ed Weiler: I must say uh, after we launched it and found out that we had an optical problem, I didn’t think we’d be here today 20 years later, talking about the great successes that Hubble has achieved.

愛德華?威勒：其實(shí)當(dāng)初我們發(fā)射哈勃望遠(yuǎn)鏡不久就發(fā)現(xiàn)它有光學(xué)問題。沒想到20年后的今天，我還有機(jī)會(huì)和你談?wù)撍妮x煌成就。

Weiler said that Hubble has taken images of the universe that are ten times clearer than any ever produced by telescopes on the ground.

威勒說，哈勃望遠(yuǎn)鏡比地基望遠(yuǎn)鏡觀測(cè)到的空間影像清晰10倍。

Ed Weiler: It’s like we’ve been near-sighted for the whole history of humankind. And we suddenly put on our glasses and have 20-20 vision on the universe. So we’ve seen, literally seen things we’ve never seen before, as nearby as pictures of, you know, our planets, to stars in our own galaxy, to other galaxies, and almost back to the very beginning of time.

愛德華?威勒：整個(gè)人類歷史上，我們對(duì)宇宙的觀測(cè)處在一種近視的狀態(tài)，哈勃望遠(yuǎn)鏡就像一副眼鏡，它使我們恢復(fù)了最好的視力，看清以前未曾看見的東西。從此我們得以觀測(cè)行星，銀河系，河外星系，乃至宇宙起源時(shí)的狀態(tài)。

The Hubble was refitted with new instruments in 2009. EarthSky asked Dr. Weiler what he expects from it in the years to come.

2009年哈勃望遠(yuǎn)鏡經(jīng)過了一次維修，部分儀器得到更換。此后它將給人類帶來什么樣的新發(fā)現(xiàn)呢？記者就這一問題采訪了威勒博士。

Ed Weiler: You know, when you’ve got something this powerful, and a universe that’s not quite infinite but almost infinite, I’m not gonna make any predictions about what we’re gonna discover because by definition.

愛德華?威勒：宇宙并非無限卻近乎無窮，人類掌握了如此強(qiáng)大的工具來探索它。我不會(huì)做任何關(guān)于宇宙新發(fā)現(xiàn)的預(yù)測(cè)，因?yàn)榘l(fā)現(xiàn)本身就是對(duì)未知事物的探索。
