A Globular Cluster in the constellation Hercules, M13 is a distance of 20,000 LY from Earth.  Also known as the Hercules
Cluster, it contains 100,000 stars and is estimated to be 150 LY across.  Globular Clusters consist of the oldest stars in our
galaxy., forming when interstellar gas and dust were far more prevalent.  These old clusters circle the center of our galaxy like
gnats circling a yard light.  M13 is one of the most prominent Globular Clusters in the sky and is 12 billion years old.
