Two galaxies, known collectively as Arp 87, are one of hundreds of known interacting and merging galaxies.

合称Arp 87的两大星系，他们是数百已为人知的正在相互作用和相互融合的星系之一。

Galaxies are a special case, as adjacent galaxies are considered to be 200 lightyears apart regardless of the exact location of the astros inside of them.

银河之间是特殊的案例，相距的两个银河之间的距离被确定为200光年，而不用去计算基地位于银河内的哪个位置。

About 210,000 light-years distant in the constellation Tucana, it is the fourth closest of the Milky Way's known satellite galaxies, after the Canis Major and Sagittarius Dwarf galaxies and the Large Magellanic Cloud.

硫元素放射出的光显蓝色，氢元素是绿色，氧元素是红色的。

The Cartwheel is part of a group of galaxies about 400 million light years away in the constellation Sculptor (two smaller galaxies in the group are visible below and left).

车轮星系位在玉夫座内，是离我们四百万光年远一个星系团的成员之一。

The other important observation we need to make about spiral galaxies is that galaxies do not rotate rigidly (with a constant angular velocity), but to a good approximation each region rotates with the same tangential velocity.

另一个重要的观察，我们需要作出关于螺旋星系是宇宙不旋转严格，但有一个良好的逼近各地区轮流担任相同的切向速度。

The Antennae Galaxies (also known as NGC 4038/NGC 4039) are a pair of galaxies about 68 million ly away in the constellation Corvus.

最近史匹哲太空望远镜的观测显示，在双天线状星系的中心有许多新生的恒星在形成，尤其是在NGC4038和NGC4039交迭的地方。

By the year 3,000,000,000,000, all that will be left for astronomers to observe will be the stuff that today makes up our gravitationally bound 'local group' of galaxies: the Milky Way and Andromeda, the Large and Small Magellanic Clouds , and a few other puny galaxies.

到公元3，000，000，000，000年，天文学家所能够观察到的将只剩下我们的本星系团，其中的星系由引力束缚在一起，包括：银河系和仙女座、大小麦哲伦星系和其他几个小星系。

The results show that the mass density of disc galaxies increases an order of magnitude from the early-type disc galaxies to the later one, oblateness decreases to minimum at Sd,m, and then increases Having excepted SO and IrII, these parameters vary with the type of disc galaxies monotonicly.

早先得出早型盘星系的质量密度要比晚型高一个量级Ⅲ。这是因为所用的质量值是光度质量，早年得到的早型星系的质光比大于晚型星系一个量级。然而后来的工作发现盘星系的质光比大约为同一值嘲。后来有

If we consider a space uniformly filled with masses, as, for example, our space is filled with stars, galaxies and clusters of galaxies, we must conclude that, apart from localized large curvatures near particular stars or galaxies, space should possess an overall curvature due to the combined effect of all the masses- a regular tendency to curve uniformly over large distances.

如果我们考虑一个空间，被不均匀的质量块填充着，比如说，像我们的空间，被恒星、星系、和星系团填满，我们得出这样一个结论：除了局部在特殊的恒星或星系附近曲率很大的地方外，由于所有的质量块共同作用，空间应该有一个总曲率-一个在远距离上连续而不均匀的弯曲的趋势。

Galaxies, cluster of galaxies, early-type galaxies, late-type galaxies, star formation rate

星系，星系团，早型星系，晚型星系，恒星形成率

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。
