这是宇宙有史以来从未出现过的现象：一颗地下流星。

This would be something never before seen in the history of the universe : an underground shooting star .

天文学家探测到宇宙中有史以来最为明亮的一次爆炸。

Astronomers have detected the brightest explosion ever witnessed in the heavens .

马道将他的结果与原有的低红移可见光观测结果合并，使得对宇宙恒星形成史的估计精确度提升。

Madau combined his results with those from existing lower-redshift optical observations to refine the estimates of the star formation history of the universe .

因为望远镜在观测非常遥远的恒星和星系时，就好像在回溯过往，因此天文学家可藉由观测遥远的天体，一窥宇宙的膨胀史。

Because telescopes look back in time as they gather light from far-off stars and galaxies , astronomers can explore the expansion history of the universe by focusing on distant objects .

在至少就我们所了解的宇宙而言，人类在特别是最近6000年里所达到的认识，在宇宙史上是一些全新的东西。

What he has achieved , especially during the last 6000 years , is something utterly new in the history of the Cosmos , so far at least as we are acquainted with it .

我们不可能知道整个宇宙到底有多大，也许宇宙中存在更为遥远的区域。但是，光线在宇宙有史以来所传播的全部距离是个极限，我们无法看得更远。

There may be parts of the universe that are farther away ( we can 't know how big the whole universe is ), but we can 't see farther than light could travel over the entire age of the universe .
