Hoag's object is a ring galaxy.

A ring of blue stars circle the yellow nucleus of this galaxy. The galaxy is about 120,000 light-years wide, which is slightly larger the Milky Way Galaxy. The gap separating the two stellar populations may contain some star clusters that are almost too faint to see. Another ring galaxy can be seen, through Hoag's object, at the 1:00 position.
