Sometimes these clusters collide and merge with one another.
有时，这些星系团之间会发生碰撞，并合二为一。
Shara's research interests include stellar collisions, novae and supernovae, and the populations of stars that inhabit star clusters and galaxies.
夏拉的研究兴趣包括恒星碰撞、星与超新星，以及星团和星系内恒星的数目分布。

基于碰撞概率的分布式卫星碰撞检测评估方法
Collisions also can transform the shape of galaxies involved; specifically, the merger of two spiral galaxies may produce a single elliptical galaxy.
碰撞也会改变星系的外形，特别是当两螺旋星系融合后可能会产生单一的椭圆星系。
Mergers of two colliding galaxies often cause starbursts, a huge but temporary increase in the rate of star formation.
当两个星系因碰撞而融合时，常会产生星爆，也就是恒星的形成速率会暂时急遽增加。

In general, galaxies do not form in isolation, and galactic collisions and mergers complicate matters considerably.
一般来说，星系并不会孤立地形成，而星系间的碰撞与合并则将事情大大地复杂化。
But that does not mean collisions are uncommon.
但这并非表示恒星碰撞是不寻常的。

Continued coffisions eventually produced planets, and the leftover comets and other debris were scattered outward toward the periphery of the solar system.
持续不断的碰撞最终形成了行星，而剩余的慧星和其它残骸则向外散落到太阳系的边缘地区。
Some scientists believe they will eventually collide with the Milky Way and become part of our own galaxy.
一些科学家认为最终这两个星云将与银河相碰撞并融为我们所在这个星系的一部分。
The composite image at left shows that this hot gas (red) was dragged away from the stars and galaxies (blue) during the collision .
上面的复合图像显示出在碰撞中炽热气体（红色）被扯离开星体和星系（蓝色）。
Because the distances are so large, the cosmic interaction takes place in slow motion-- over hundreds of millions of years.
由于这些星系都很巨大，所以它们的碰撞是一种慢动作过程，通常要经过数亿年才会完成。
Given enough time, the tightly packed stars will begin to collide.
只要时间够长，这些密集的恒星将开始碰撞。
