M2 • NGC 7089 • Globular Cluster

M2 is one of the largest and most impressive globular clusters in the northern sky. It contains several hundred thousand ancient stars packed into a dense, bright core surrounded by a rich halo of fainter members. The cluster’s high stellar density and smooth radial structure make it a rewarding target for both visual observers and astrophotographers. Its stars are predominantly old and metal-poor, offering a glimpse into the early evolutionary history of the Milky Way.
