The Universe Today : Whirlpool Galaxy

This picture was taken overnight of the Whirlpool galaxy (NGC 5194) and you can see it’s companion galaxy (NGC 5195) above it. The smaller galaxy is gravitationally bound to the Whirlpool Galaxy and constantly orbits the larger galaxy, at times even passing hrough the Whirlpool Galaxy itself. Millions of years in the future these two galaxies will combine to form one single galaxy much like our Milky Way galaxy will do when it collides with the Andromeda Galaxy.

We processed the image below to show the older stars (red) and the young blue stars which exist in these two galaxies.
