It's the 20th anniversary of the Hubble telescope. So, the featured images tonight are from Hubble. This photo is Stephan's Quintet, a group of galaxies located in the constellation Pegasus.
This is the Cat's Eye Nebula, and from Hubble's site: "One of the first planetary nebulae discovered, it also has one of the most complex forms known to this kind of nebula. Eleven rings, or shells, of gas make up the nebula. The Cat's Eye Nebula is about 1,000 years old, and could have resulted from a double-star system."
