APOD 3.07

This is a picture of a polar ring galaxy. It's is very rare and it has a ring of gas, stars, and debris that orbit in a flat disk perpendicular to the plane of the galaxy. It is believed to be a chance capture; a galaxy ran into it, and the debris was captured and strung into a rotating ring. The ring of NGC 2685 is very old and very stable. In this picture of Arp 336, the rings are very easy to see, along with other odd structures.
