The Hercules Globular Cluster, also known as M13, is a dense collection of stars located in the constellation Hercules. It is approximately 25,000 light-years away from Earth and contains around 100,000 stars. This cluster is one of the brightest and best-known globular clusters in the night sky. Discovered by Edmond Halley in 1714, the Hercules Globular Cluster is about 13 billion years old, making it one of the oldest known star clusters. Its stars are tightly packed, which creates a unique environment for studying stellar evolution and dynamics. The cluster is best viewed during the summer months in the Northern Hemisphere.
