查询词典 galaxies

Most galaxies abound with interstellar gas and dust, the detritus of countless generations of stars.

绝大多数星系有着丰富的星际气体和尘埃，这些都是无数代恒星散落下来的物质材料。

As a result, galaxies in clusters become starved of gas over time, and black hole activity and star formation in these galaxies slows.

结果，随着时间的推移，星系团内的星系就会缺乏气体，因此这些星系中黑洞的活跃性减弱，新星的形成速度放慢。

The current picture is that all galaxies may have a supermassive black hole in their center, and that this black hole swallows gas and dust in the middle of the galaxies generating huge amounts of radiation - until all the nearby mass has been swallowed a

现在的照片是所有的星系在它们中心可能存在超大质量的黑洞，而且这个黑洞在星系中心吞咽气体与尘埃产生极大量辐射-直到所有附近质量被吞咽，而且过程停止下来。

Comparing to other galaxies,these host galaxies of H2O masers may have some special properties not yet to be noticed.

同其它没有检测到水脉泽的星系相比，水脉泽星系可能隐含着某种或某些特殊性质。

Radio galaxies and quasars, Seyfert galaxies are similar, but there are differences.

射电星系与类星体、塞佛特星系有相似之处，但又有区别。

I study images of quasars giving birth to galaxies, galaxies whirling in the shapes of pinwheels, supernovas ringed by strands of luminous debris

我研究类星体产生星系的图像，这些星系如同玩具风车一样旋转，超新星周围是一条条由星体遗骸组成的闪闪发光的带状物

With galaxies, the slower the smash-up, the more violent the collision, since gravity has more time to pull the two galaxies into an inescapable bind.

因为重力有充裕的时间将两个星系牵引成不可避免的一个整体，所以对于星系未说，撞击得越慢，就越猛烈。

First, you will look at a few galaxies in the SkyServer database. You will measure their magnitudes to get a rough idea of their distances. You will use these distances, along with SkyServer's measurements of the galaxies' redshifts, to make a simple Hubble diagram.

首先，你将在 SkyServer 数据库中看到一些星系，你将测量他们的星等以获得它们距离的粗糙数据，你将使用这些数据和 SkyServer 中测量的红移得到一件简单的哈伯列表。

Unlike more local galaxies, which are visible in the bluer filters as well,the very large 'redshifts' of galaxies at the edge of the observable universe mean that no light is emitted at the blue end of the spectrum.

与能够在蓝光段完整看见的我们周围的星系不同，在可观测宇宙边缘附近的星系红移相当巨大，它们的辐射都无法在蓝光段看见。

After Edwin Hubble discovered in 1929 that the distances to far away galaxies were generally proportional to their redshifts, as suggested by Lema tre in 1927, this observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity.

在埃德温哈勃在1929年发现的距离遥远的星系一般都是成正比的红移秒，所建议的勒梅特于1927年，这一观察表明，采取非常遥远的星系和星系有一个明显的速度直接远离我们的优势点：更远，更高速度的明显。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
