      Description

      One of the brightest and best-known globular clusters in the world northern sky. This glittering metropolis of stars is easily found in the sky in the constellation Hercules and can even be glimpsed with the unaided eye under dark skies.

      M13 is home to over 100,000 stars and located at a distance of 25,000 light-years. These stars are packed together in a ball, approximately 150 light-years across, that they will spend their entire lives whirling around in the cluster.
