Hoag's Object (Picture of the Day: 1/16/13)

This strange galaxy was the first ever ring galaxy to be identified. The outer ring is composed of bluish stars, and the center glow is a "dense" ball of bright, yellow-red stars. The dark area between the ring and the center appears to be almost entirely empty. It is still not known how these objects form, but they are not overly rare. One thing is for certain, they look cool.
