In today's image, we see the spiral galaxy known by the catalog designation of NGC 1512. This is an example of a ring galaxy - we see two rings here. The central ring is Called the Nuclear Ring and the ring further out is called the Inner Ring. Some galaxies have a ring even further out which is called the Outer Ring.
