This is the globular cluster known as M15 in the constellation of Pegasus. A globular cluster is a large grouping of stars held together by only their own gravity. This particular cluster is about 35,000 light years away, consists of more than 100,000 stars and, like most globular clusters, dates back billions of years to the early days of the Milky Way galaxy. M15 is noted for being easily visible with binoculars and has one of the densest known star concentrations near its center, which recent evidence suggests actually contains a black hole.
