2013 November 19

Over 100,000 stars swarm together in the center of the bright cluster, M15. Formed from the very early years of our Galaxy, and still orbits the center of our Galaxy. At its center, it has one of the densest concentrations of stars known, with a high abundance of variable stars and pulsars. This image spans 120 light years, as M15 lies 35,000 light years
away towards the constellation of Pegasus.
