As kids, many of us pondered what stars are made of.
孩提時代的我們大多都會思考星星到底是由什么做成的。
Some grown-up astronomers, on the other hand, wonder about where stars came from.
另一方面，一些已經(jīng)成為天文學(xué)家，曾經(jīng)的孩子則好奇星星們是從何而來。
Now, a study serves up a surprise.
而現(xiàn)在一項研究已經(jīng)給出了令人吃驚的答案。
Because it seems that the smallest galaxies in the universe gave rise to an unexpectedly large proportion of stars.
因為結(jié)果顯示宇宙中最小的星系產(chǎn)生了意想不到的大部分星星。
The findings are in the Astrophysical Journal.
這項研究已在《天體物理學(xué)雜志》上發(fā)表。
Most of the stars we see in the sky were formed when the universe was young, just a few billion years after the Big Bang.
我們看到的天上的大部分星星都是在宇宙年輕時形成的，也就是宇宙大爆炸過后的那幾億年里所發(fā)生的事。
So to study stellar origins, scientists use telescopes that allow them to see galaxies that are so far away, they're essentially looking back in time.
所以為了研究它們的起源，科學(xué)家們使用了天文望遠鏡觀測到距離很遠的星系，他們必須要追憶一下過往的歲月。
Previous observations had focused on the star-forming powers of larger galaxies.
之前的觀測重點都是集中在更大星系中形成星星的能量。
But in this latest study, researchers used data collected by a powerful camera aboard the Hubble Space Telescope.
但是在最近的研究中，研究人員們使用了哈勃天文望遠鏡上安裝的超級相機采集到的數(shù)據(jù)。
With this instrument, they could eyeball smaller, dwarf galaxies.
有了這個設(shè)備，研究者們便可以仔細觀察較小的矮星系。
And they found that these diminutive dynamos churned out stars at a furious rate, fast enough to double their mass in only 150 million years.
而他們發(fā)現(xiàn)這些小型發(fā)電機以近乎瘋狂的速度制造著星球，在只有一億五千萬年的時間里其質(zhì)量就已翻倍。
That reproductive feat would take most so-called “normal” galaxies one to three billion years.
這樣的高產(chǎn)率也許可以在未來1到3億年時間里制造出更多的正常星系。
Seems the universe has long known what Danny Devito, Michael J. Fox and Dustin Hoffmann later proved:
莫非宇宙早已經(jīng)洞察到Danny Devito, Michael J. Fox 和Dustin Hoffmann給世人所作出證明：
You don't have to be big to have real star power.
濃縮的精華力量無窮。
