Messier 56
Messier 56 - A globular cluster in the constellation Lyra. Discovered by Charles Messier on January 19, 1779.
It is at a distance of around 32,900 light-years from Earth and measures roughly 84 light-years in diameter, with a combined mass of approximately 230,000 times that of the Sun. The cluster has an estimated age of around 13.70 billion years. It is thought that this cluster may have been acquired during the merger of a dwarf galaxy, of which Omega Centauri forms the surviving nucleus.
