Messier 5 (M5) is a spectacular globular cluster located in the constellation of Serpens. It is one of the oldest and largest globular clusters in the Milky Way galaxy, situated at a distance of approximately 24,500 light-years from Earth. M5 is home to hundreds of thousands of stars densely packed within a spherical region, gravitationally bound together. It has a distinct core surrounded by a halo of stars that extend outward. With an estimated age of around 13 billion years, M5 is among the oldest known globular clusters. This cluster is a favorite target for amateur and professional astronomers alike due to its brightness and its beautiful appearance in telescopes. Its proximity and large size make it easily visible even with small telescopes or binoculars under dark skies. Studying M5 provides valuable insights into the formation and evolution of globular clusters, as well as the dynamics of stars within these ancient stellar systems. It serves as a window into the early history of our galaxy and the universe.
