Messier 13, in the constellation Hercules, is a globular cluster of hundreds of thousands of stars.  It is a spectacular sight in moderate sized telescopes, looking rather like diamonds sprinkled on black velvet. The cluster is about 24,000 light years from earth and approximately 145 light years in diameter.
