What is the official designation of the Crab Nebula in the catalog created by Charles Messier?

Answer

Messier 1

The Crab Nebula is historically significant in astronomy for being the very first entry, known as Messier 1, in the catalog compiled by Charles Messier. This catalog was created to help observers distinguish between static nebulous objects and moving objects like comets, and the inclusion of the Crab Nebula at the top of the list highlights its prominence and brightness among deep-sky objects.
