M13 is located 25,000 light years away in the constellation Hercules. The cluster is visible from a dark sky with a pair of binoculars. M13 is one of the brightest globular clusters visible from the Northern Hemisphere. This cluster is composed of 300,000 stars orbiting outside the plane of our Milky Way Galaxy. M13 is typical of a globular cluster with hundreds of thousands of stars packed together in a small area. Such clusters populate the halo of most galaxies. Our own Milk Way Galaxy contains at least 150 more of them, but the stars in these densely packed clusters are older then the typical young stars found in clusters along the galactic plane. Globular clusters are somewhat of a mystery. Their origins and galactic evolution is still not clear. Located near M13 is the small galaxy NGC6207.
