The Messier Objects

Messier Objects are a catalog of astronomical objects compiled by the French astronomer Charles Messier in the 18th century. The list includes nebulae, star clusters, and galaxies, totaling 110 distinct objects. Originally created to help astronomers distinguish between permanent celestial bodies and transient comets, Messier Objects are now popular among amateur astronomers. Each object is numbered (like M1 for the Crab Nebula) and showcases the diversity of the universe, serving as important targets for observation and study, revealing insights into the structure and evolution of the cosmos.
