M53 Globular Cluster in Coma Berenices

Messier 53 (M53) is a globular star cluster located in the northern constellation Coma Berenices. The cluster is almost 60,000 light years from Earth. It contains at least 500,000 stars.

The stars in the cluster are considered metal-poor, as they contain very little quantities of elements heavier than helium, which is below average for stars found in a globular cluster.
