The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his Catalogue des Nébuleuses et des Amas d'Étoiles (Catalogue of Nebulae and Star Clusters). Because Messier was interested only in finding comets, he created a list of those non-comet objects that frustrated his hunt for them.
Charles Messier. Charles Messier (French: [ʃaʁl me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer. He published an astronomical catalogue consisting of 110 nebulae and star clusters, which came to be known as the Messier objects, referred to with the letter M and their number between 1 and 110. Messier's purpose for the ...
The Messier Catalogue was a list of astronomical objects compiled by Charles Messier between 1771 and 1781, in which he briefly described each object and provided their coordinates on the sky. Because Messier was only interested in finding comets, he created this list of non-comet objects that frustrated his hunt for them.
Messier 3 is the prototype for the Oosterhoff type I cluster, which is considered "metal-rich". That is, for a globular cluster, Messier 3 has a relatively high abundance of heavier elements. [ 15 ] Arcturus and Cor Caroli can be used to help locate M3.
Articles with the Messier number in the title use [[Category:Messier objects|###]], dropping the M prefix, and using only the number. The number should be padded up to 3 digits using zeroes. Articles without the Messier number in the title use [[Category:Messier objects]]. A redirect containing the Messier number should also be added to the ...

See also: Lists of nebulae. The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum–Centaurus Arm. [3] It was discovered by Charles Messier on June 5, 1764. [4] Its name means 'three-lobe'. The object is an unusual combination of ...
The location of the Small Sagittarius Star Cloud is near the Omega Nebula (also known as M17) and open cluster Messier 18, both north of M24. M24 is one of only three Messier objects that are not actual deep sky objects. [6] M24 fills a space of significant volume to a depth of 10,000 to 16,000 light-years.
