1·If the center of NGC 4258 were a star cluster, the stars would be so closely spaced that collisions between individual stars would have long ago torn the cluster apart.

如果 NGC 4258 的中心是一个星团，恒星之间的距离会非常近，以至于在很久以前单个恒星之间的碰撞就会把星团撕裂。

2·A galaxy or a star cluster consists mainly of the stars.

星系和星团主要由恒星组成。

3·In September, this star cluster is up late at night, or before dawn.

在九月，这组星星在深夜或黎明前升起。

4·The star cluster is embedded in a nebula, which spans some 110 light-years.

该星团嵌在一个约110光年大的星云内。

5·The giant was identified at the centre of a star cluster in the Tarantula Nebula.

这颗巨大的恒星位于大麦哲伦星云的一个星团的中心。

6·Star cluster grouping from the candidate star centers speeds up the procedure of star acquisition.

以初步位置为基础的星图像素聚类加速了星图中星的获取过程。

7·Can you find, in the above image, a comet, a spiral galaxy, an open star cluster, and a supernova remnant?

在上面图中，你能找到：一彗星，一旋涡星系，一疏散星团和一超新星遗迹吗？

8·They stumbled on it in a star cluster called Westerlund 1, which is located 16,000 light-years from Earth.

他们在一个叫韦斯特伦德1号星团（距离地球16000光年）无意中发现这颗磁星。

9·About a third of the way along this line, you'll find a hazy object, an open star cluster, called M50.

沿着此线大约三分之一处，你会发现一个模糊的物体，它的名称为M 50，是个散开星团。

2·Featured in this sharp telescopic image, globular star cluster Omega Centauri (NGC 5139) is some 15, 000 light-years away.

这幅高清望远镜图像显示的是距地15 000光年的半人马座欧米伽球状星团（NGC 5139）。

3·Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15.

当然，这些云气是由恒星风和辐射塑造成的，这些恒星风和辐射来自于星云新诞生的梅洛特15号星团的大量炽热恒星。

4·The Pleiades is an open star cluster, which means that while its stars are bound loosely together right now, each star will eventually go its own way within a few hundred million years.

昴宿星团是个开放性的星团，这意味着虽然它内部的恒星目前松散地聚在一起，但是在未来数百万年的时间内，每颗恒星最终依照自己的轨道运行。

5·Remarkably, the ion tail easily stretches past background star cluster NGC 1245 (upper left) in the constellation Perseus, about 1.5 degrees from the comet's lovely greenish head or coma.

明显地，离子彗尾轻易伸展至背景星团NGC 1245（上左）的前面，在飞马座，离彗星可爱的绿色彗头或彗发1.5度。
