M13 is perhaps the most famous globular cluster in the Northern Hemisphere.   The cluster is
estimated to contain1http://www.seds.org/messier/m/m013.html  as many as a million stars.  
These stars orbit each other wildly in a ball of approximately 100 light years in diameter.  This
globular is composed of some of the oldest stars in the Universe.  They are estimated to be
over 12 billion years old.  The cluster is located about 25,000 light years from the earth in the
direction of the constellation Hercules.
