矮星系

矮星系（Dwarf galaxies）：2个行星状星云：4个（M27、M57、M76、M97）超新星残骸：1个（M1）弥漫星云：7个（M8 …

侏儒星系

它是天文学家在深空探索中找到的大量「侏儒星系」(dwarf galaxies) 中的一员，这些「侏儒星系」比其它典型星系（如我们的 …

矮星云

而矮星云（Dwarf Galaxies）之形成，则并非由於初期宇宙中气团之分裂。一般认为此种矮星云乃由巨形星云所引起。

For another , the clouds don't look like the disheveled spheroidal dwarf galaxies that closely orbit the Milky Way and other major spirals.

另一方面，这些星云看上去并不像结构松散的球状矮星系一样紧紧地围绕银河系和其它主要的漩涡星系的轨道运行。

4

Which of the dwarf galaxies we find today were already in existence at the beginning?

我们今日所见的矮星系，哪一个是在很早以前便已存在了呢？

5

We would like to see if MOND can explain the apparent scarcity of dwarf galaxies in our neighbourhood .

我们想看看「修正牛顿力学」能否解释我们附近缺乏矮星系的现象。

6

Such encounters between dwarf galaxies are normally seen billions of light-years away and therefore occurred billions of years ago .

矮星系之间的如此遭遇通常发生在几十亿光年之外，也就是几十亿年之前。

7

Warm gas moves faster than cool gas , and the heated helium sped free of the gravitational clutches of so-called dwarf galaxies .

热气比凉气运动得快，而炽热的氦气几乎不受所谓的矮星系重力的束缚，能够自由运动。

8

Hierarchical theories predict a proliferation of low-mass dark matter halos and, by extension, dwarf galaxies .

阶式理论预测低质量的黑暗物质晕应该很多，矮星系也是一样。

9

The problem is dwarf galaxies are not as dense as the cold dark matter model says they should be.

问题在于矮星系并没有它们本应具有的冷暗物质的密度。

10

So dwarf galaxies would presumably exhibit the cusp of dark-matter particles in their centers that spirals lack .

所以矮星系在其中心可能存在着暗物质的尖点而螺旋星系不太可能。
