Messier Objects
The Messier objects are a collection of 110 astronomical objects cataloged by the French astronomer Charles Messier in the late 18th century. Initially compiled to help distinguish between permanent celestial bodies and transient comets, the list has become a vital resource for amateur and professional astronomers alike. The catalog includes various types of deep-sky objects, such as galaxies, nebulae, and star clusters, all located within our Milky Way and neighboring galaxies.
