By measuring the motion of the galaxies in a cluster, astronomers can infer the cluster's mass.通过测量星团中星系的运动，天文学家可以推断出该星团的质量。Since the universe began, the galaxies have gradually moved further apart.从宇宙开始的时候起，星系之间就逐渐地越来越远。Man is physically infinitesimal compared to the billions of stars and galaxies.人类就有形肉体与亿兆星球和星系相比，实在是渺小之极的。They turned their telescopes towards other nearby galaxies.他们把望远镜转向附近其他星系。They hypothesise that galaxies must contain a great deal of missing matter which cannot be detected.他们假定各星系必然含有大量无法探测到的失踪物质。Edwin Hubble discovered that distant galaxies are moving away from us.埃德温·哈勃发现远处的星系正在远离我们。The telescope can detect light emitted by distant galaxies.望远镜能观测到遥远星系发出的光。Galactic surveys show that distant galaxies are not as evenly distributed in space as theory predicts.对银河系的研究表明，遥远星系在太空中的分布并不像理论所预言的那样均匀。This law is known to hold true for galaxies at a distance of at least several billion light years.已知这条定律同样适用于距离至少几十亿光年远的星系。Some galaxies seem to release prodigious amounts of energy.一些星系似乎释放出巨大的能量。Most galaxies are found in clusters rather than in isolation.大多数星系都成星团存在，而不是孤立的。Space is filled with unknown stars and uncharted galaxies.宇宙中满是未知的星球和未标明的星系。The telescope can detect light given off by distant galaxies.这台望远镜能观测到遥远星系发出的光。There were specks of light beginning to form galaxies.有一些开始形成星系的小光斑。To explain this, they hypothesise that galaxies must contain a great deal of missing matter which cannot be detected.为了解释这一点，他们假定各星系一定包含了大量无法探测到的不明物质。Quasars are the highly energetic cores of distant galaxies.类星体是遥远星系的极为活跃的核心体。The telescope is so powerful that it can show up galaxies billions of light years away.这架望远镜性能强大，可以使人看见数十亿光年外的星系。 |
