Messier object. 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 ...
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 ...
Messier 83. Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy [7] approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope. [8]
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.
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 ...
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'.
In 1781, the French astronomer Charles Messier published a catalogue of 103 objects that had a nebulous appearance as part of a list intended to identify objects that might otherwise be confused with comets. In subsequent use, each catalogue entry was prefixed with an "M". Thus, M87 was the eighty-seventh object listed in Messier's catalogue. [15]
The nebula was independently rediscovered in 1758 by Charles Messier as he was observing a bright comet. [10] Messier catalogued it as the first entry in his catalogue of comet-like objects; [10] in 1757, Alexis Clairaut reexamined the calculations of Edmund Halley and predicted the return of Halley's Comet in late 1758.
