1·Near the quasars in time are other, normal galaxies that have likely just passed through a quasar phase, as seen in images released earlier this month.
本月早些时候公布的一些图片显示，在类星体周围适时出现的，是其他那些正常的，刚刚经历了类星体阶段的星系。
2·Which came first, the quasar or the galaxy?
类星体和星系哪一个形成在前呢？
3·So when a quasar goes dormant, what's left are the things we associate with a normal galaxy — stars and gas swirling around a central and hidden pit of matter.
因此当一个类星体趋于休眠，留下来的就是我们通常和一个正常的星系联系起来的东西——星星和气体，他们围绕着一个隐藏着物质的大洞形成一个漩涡。
4·In our current picture, as every galaxy forms and collapses, it has a brief quasar phase.
在我们目前所掌握的星系建立和毁灭的图景中，存在着一个短暂的类星体阶段。
5·Scientists were checking out a quasar, an incredibly distant, incredibly bright object. This quasar was the only one without a known host galaxy.
科学家们在研究一种距离遥远，亮度超常的类星体，它是唯一没有已知宿主星系的恒星状球体。
