星系

So the galaxy will keep growing until it envelops the quasar itself.

所以这个星系将不断攀升，直到它包围了类星体。

That the vast amount of energy spewing from its bright quasar would literally force the rest of the galaxy out of its reach.

这样的时候：从它的明亮的类星体中释放出来的巨大能量不断迫使星系内其他部分摆脱它的控制。

The gravitational field of the visible foreground galaxy breaks light from this distant quasar into four distinct images.

前景星系的巨大引力场使这颗遥远的类星体发出的星光被弯曲成四个不同的影像。

These include a black hole at the center of a nearby galaxy and the discovery of what some scientists are calling an entirely new type of quasar.

这其中包括探测到一个附近星系中心上的黑洞，以及发现被一些科学家称为一种全新种类的类星球体。

Which came first, the quasar or the galaxy?

类星体和星系哪一个形成在前呢？

Gravitational violence during mergers mixes orbits and redistributes energies and angular momenta; the result is that quiescently formed systems such as disks are turned into ellipsoids.

合并期间引力作用混合了彼此的恒星并且重新分配了角动量；其结果是被迫合并的系统变成了椭圆星系。

The disturbed looking group of galaxies at the lower left is well-known as Stephan's Quintet .

左下角有外表扭曲的星系群，他们是著名的 Stephan 五胞胎。

Radio astronomy has greatly increased our understanding of the universe.

天文学方面最新发展使得我们能够在银河系和其他星系发现行星。

To help them in this seemingly impossible endeavor, the researchers used radio astronomy data, which provided the relative speeds at which the galaxies and their constituent parts are currently moving.

为了给他们这种令人难以置信的努力提供帮助，研究人员使用了射电天文学的资料，这种资料为星系以及组成部分当前的运行提供了相关速度。

Dual-source radio galaxies of the universe in essence, the brightest celestial radio emission.

双源射电星系是宇宙中本质上最亮的射电辐射天体。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
