Incredible Image Taken of Super-Dense Star Cluster

This incredible image, made up of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys, is of a cluster of stars known as Messier 15. The cluster is about 35,000 light-years away from us in the constellation Pegasus and is one of the oldest globular clusters known at about 12 billion years (you should go back and read that in Carl Sagan’s voice, of course).

Perhaps we shouldn’t be so astounded by images such as this, since there are an estimated 1 x 10^24 (that’s 1 septillion) stars in the observable universe.
