M13, Hercules Star Cluster

M13, Hercules Star Cluster

Cluster of Lights

The image above is that of M13, “The Great globular cluster in Hercules”. This gravitationally bound cluster lies about 25,000 light-years away from us within the Milky Way Galaxy, and is comprised of several hundred thousand stars. These are older, Population II stars, many of which have left the main sequence and are now red giants. Globular clusters, such as M13 are most common in the Halo of our galaxy that surrounds the core. The varying colors present in this image are reflective of the differing temperatures and sizes of stars comprising the cluster. Another, smaller galaxy, IC 4617, can be seen above and to the right of M13. It is a 16th magnitude galaxy. (Image published in May 2012 edition of Astronomy Magazine, Deep Sky Showcase)
