Posted on 03/17/2014 7:32:12 AM PDT by SunkenCiv
Explanation: Two galaxies are squaring off in Corvus and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. That's because galaxies are mostly empty space and, however bright, stars only take up only a small amount of that space. During the slow, hundred million year collision, one galaxy can still rip the other apart gravitationally, and dust and gas common to both galaxies does collide. In this clash of the titans, dark dust pillars mark massive molecular clouds are being compressed during the galactic encounter, causing the rapid birth of millions of stars, some of which are gravitationally bound together in massive star clusters.

Thank You, Sunken Civ!
Whoa! Smackdown on a galactic scale!
This appears to be post-collision and the two galaxies are going their separate ways. You can still see the galactic centers of both galaxies. The galaxy in the top of the photo looks like it’s kept a good part of its structure, but the one in the bottom has been ripped apart.
