science:

A computer simulation of what happens when two spiral galaxies collide. At various points, the simulation stops to show a comparison to pictures of actual galaxy pairs in the midst of this process, as seen from the Hubble telescope. In a few billion years, the Milky Way might undergo this process, merging with our largest neighbor, the Andromeda Galaxy.
