Globular Cluster M15 from Hubble
Stars swarm around the center of the bright globular cluster M15. This ball of over 10,000 stars is still here from the earliest years of our galaxy and continues to orbit the Milky Way's center. M15 is one of only 150 globular clusters remaining and can only be seen with binoculars. It's center has one the densest concentrations of stars known and contains a high abundance of variable stars and pulsars. This image was taken by the Hubble Space Telescope and spans about 120 light years.
