APOD 2.4

Atoms-for-Peace Galaxy Collision

This is a picture of NGC 7252, the result of two large galaxies colliding.  The full collsion will take hundreds of millions of years.  The combined galaxies has been given the nickname "Atoms-for-Peace" because it looks similar to a giant atom.  Atoms-for-Peace spans about 600,000 light years and is about 220 million light years in the direction of the constellation Aquarius.  It is not unlikely that this will someday happen to our Milky Way!  Our galaxy could perhaps collide with the nearby Andromeda Galaxy!!
