For example, Messier 1 is a supernova remnant, known as the Crab Nebula, and the great spiral Andromeda Galaxy is M31. Further inclusions followed; the first addition came from Nicolas Camille Flammarion in 1921, who added Messier 104 after finding Messier's side note in his 1781 edition exemplar of the catalogue.
Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1] although two objects (NGC 4244 and the Hyades) are listed out of sequence.

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 ...
The Little Dumbbell Nebula, also known as Messier 76, NGC 650/651, the Barbell Nebula, or the Cork Nebula, [1] is a planetary nebula in the northern constellation of Perseus. It was discovered by Pierre Méchain in 1780 and included in Charles Messier 's catalog of comet -like objects as number 76.
Messier 103 is an easy object to find and the cluster is visible in binoculars or a small telescope. [8] object to find and the cluster is visible even with the use of binoculars. [4] [9] M103 can be seen as a nebulous fan-shaped patch, and is about a fifth the apparent diameter of the Moon or 6 arcminute (6′) or 0.1° across. To find M103 ...
Charles Messier noted it in 1764 and—a studier of comets—cast it as one of his nebulae. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200. [9] Messier 5 is receding from the Solar System at a speed over 50 km/s. [10]
A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep-sky objects ( galaxies , nebulae , and star clusters ).
