This list, which Messier created in collaboration with his assistant Pierre Méchain, is now known as the Messier catalogue. The Messier catalogue is one of the most famous lists of astronomical objects, and many objects on the list are still referenced by their Messier numbers. [1] The catalogue includes most of the astronomical deep-sky ...
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.

The Messier catalogue: the Messier objects are a set of astronomical objects first listed by French astronomer Charles Messier in 1771. Nebulae and Star Clusters was published in 1781, with objects M1–M110. The New General Catalogue or NGC, compiled in the 1880s by J. L. E. Dreyer, lists objects NGC 0001 – NGC 7840. It is one of the largest ...
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies , star clusters and emission nebulae .
Messier 83 captured by the Wide Field Imager at ESO's La Silla Observatory in September 2008 M83 is a massive, grand design spiral galaxy . [ 10 ] Its morphological classification in the De Vaucouleurs system is SAB(s)c, [ 2 ] where the 'SAB' denotes a weak-barred spiral, '(s)' indicates a pure spiral structure with no ring, and 'c' means the ...
The list was compiled by Patrick Moore as a complement to the Messier catalogue. [1] While the Messier catalogue is used by amateur astronomers as a list of deep-sky objects for observation, Moore noted that Messier's list was not compiled for that purpose and excluded many of the sky's brightest deep-sky objects, [1] such as the Hyades, the ...
Messier 13 was discovered by Edmond Halley in 1714, [2] and cataloged by Charles Messier on June 1, 1764, [9] into his list of objects not to mistake for comets; Messier's list, including Messier 13, eventually became known as the Messier catalog. [10] It is located at right ascension 16 h 41.7 m, declination +36° 28'. Messier 13 is often ...
