例句：

The research is expected to help nail down estimates of even bigger black holes associated with ancient distant galaxies known as quasars .

这项研究有助于人们对于更大体积的黑洞进行估计，而这种黑洞可能与名为类星体的古老星系有关。

Did you know there's a black hole in the center of our galaxy ? No Time Dilation for Distant Quasars? Galactic Monster Mystery Solved.

你知道我们银河系中心有一个黑洞吗？别瞪大眼睛搜寻那遥远的类星体 --那没用！银河系大揭秘。

The discovery suggests that quasars created at least some galaxies , and perhaps not the other way around.

该发现表明，类星体至少创造了某些星系，或许并不是星系创造了类星体。

This quasar lit up the nearby gas , and although the quasar has since gone out , the light from it is still travelling to the object .

该类星体点亮了附近的气体，虽然该类星体已经耗尽，但光仍在该物体中旅行。

The supermassive black holes that are still active , however , do not exhibit the same behavioral patterns as the distant quasars .

但是，目前仍活跃的超大质量黑洞，其行为模式与遥远的类星体并不相同。

Their colleagues might be happy probing to the edge of the cosmos looking for exotic things like black holes and quasars and dark matter .

他们的天文学同僚们或许很乐意探索宇宙的边缘以寻找奇特的物质，比如黑洞、类星体和暗物质。

They are rare , accounting for roughly one out of every 500 observed quasars .

大约每观测 500 个类星体，才会出现一个这种稀罕的类星体。

Quasars are so far away that they constitute the best frame of reference for measuring Earth's rotation rate.

到目前为止，类星体是测量地球自转最好的参照系。

The dimmest, most economical of those stars might live 10 trillion years , a thousand times as long as the sun.

这类星体中那些最暗淡最经济的成员都可能活上十万亿年，这是太阳寿命的一千倍。

A growing black hole , called a quasar , can be seen at the center of a faraway galaxy in this artist's concept.

这是一颗正在成长的黑洞，称之为类星体，它位于一个遥远星系的中心。

To do this, it will examine what happens to the beams coming from faint, distant quasars as they pass through the cosmic web .

它将检查当衰弱而遥远的类星体通过宇宙网时，从它发出的光究竟发生了什么。

They behave as scaled-down versions of much more massive black holes that are at the cores of extremely active galaxies , called quasars .

它们的表现可以极端活跃星系（称为类星体）中心的大型黑洞作为参照。

To do this , it will look at what happens to the light coming from faint , distant quasars as it passes through the web .

要做到上述这点，还要根据微弱而遥远类星体的光经过宇宙网时发生的现象而定。

The mirror , in this case , is a vast blob of gas about 70, 000 light-years away from the center of a spiral galaxy, where the quasar resides .

从这种情况看，这个大家伙实质上是来自 70000 光年之外的星系螺旋线（宇宙射线）的视像，也即是类星体所在之处。

The first one we looked for was a distortion of the wavelength scale against which the quasar spectral lines were measured .

我们第一个检查的是，测量类星体谱线时波长尺标的扭曲。

Within a few million years , both quasar and galaxy will have merged .

在几百万年的时间里，类星体和伴星系将会合并在一起。
