Discovery of the M87 galaxy

01/01/1781View on timeline

Messier 87, or M87, is one of the 110 night sky objects identified by the French astronomer Charles Messier. In 1771, Messier published an astronomical catalogue that listed all of the nebulae, star clusters and galaxies he identified; in 1781, he revised his catalogue, adding objects. The last additions, that made up the number 110, were made by contemporary astronomers in the 1960s, based on the observations of Messier.
