quasars

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。

STIS can see in ultraviolet, visible and near-infrared and has been used to examine black holes, quasars and planets.

STIS能够观测紫外、可见光和近红外波段，主要用于研究黑洞、类星体及行星。

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。

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。

The name comes from the fact that the first quasars identified emit mostly radio energy and look much like stars.

这个名字实际上来自首个被确认的类星体，它所发射的绝大部分是射电能并且看上去很像恒星。

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。

But a crucial part of the puzzle remains unsolved: How did the universe form monster quasars so early in its history?

但是，这个谜题的一个关键部份仍然悬而未解：宇宙如何能在其早期历史中形成如此巨大的类星体？

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。

But the relative abundance of quasars in the first billion years of the universe has puzzled astrophysicists.

但是，类星体在宇宙诞生的前十亿年中的相对来说很丰富一直使天文物理学家迷惑不已。

The new observations revealed hidden quasars in every one of the galaxies, the team reports online today in Science.

研究小组今天在《科学》在线版上报道说：这些新的观测显示，每个星系中都有隐藏的类星体。

Dr Webb first conducted such a study almost a decade ago, using 76 quasars observed with the Keck telescope in Hawaii.

约十年前，Webb博士在夏威夷用Keck望远镜观测76个类星体，首次进行了此类研究。

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。

The main results of the observation of quasars are shown as continuous spectrum, absorption line spectrum and emission line spectrum.

类星体的观测结果集中表现在三个方面：连续谱、吸收线和发射线。

The blue and yellow areas around the "butterfly wings" are quasars on the outer edges of observable space.

蓝色和黄色区围绕“蝴蝶翅膀”是对观察到的太空边缘外类星体。

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 quasars are so bright that they probably are consuming their energy resources at a very rapid rate.

类星体非常明亮，因而它们可能正在极其迅速地消耗它们的能源。

How can an uneducated man praise God for the wonders of crystallization or capillary attraction or metamorphosis or quasars or stalactites?

一个没有受过教育的人怎么能称赞如结晶体、毛细血管吸引、质变、钟乳石等上帝的奇迹呢？
