A Violent Whirpool in the Sky...
This galaxy is called M77. It is one of the more unusual objects in the sky. It has an extremely bright core, and puts off an incredible amount of radiation of various types, from radio to x-ray. It is pretty much agreed upon that this galaxy has a very large black hole in it's center, that is actively engaged in cosmic destruction. This galaxy and others like it are known as Seyfert Galaxies, named after the fellow who first identified them.
If you look closely at the image, not only can you see the core and the brighter parts of the arms, but there is a vague disk that extends outward for quite a distance.
