A Messier object is a celestial object, such as a galaxy, nebula, or star cluster, that was catalogued by the French astronomer Charles Messier in the 18th century. This catalog remains useful today because it provides an organized way for astronomers and amateur stargazers to identify and study some of the most interesting deep-sky objects visible from Earth.
