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.
Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.
Among those who saw the comet was the thirteen-year-old Charles Messier, on whom it had a profound and inspirational effect. He went on to become one of the founding figures of modern astronomy , and later discovered many comets during his observations.
C/1769 P1 (Messier) is a long-period comet that was visible to the naked eye at its last apparition in 1769. The comet is classified as a great comet due to its superlative brightness. Discovery and observations
Comet Messier–Méchain, also known as C/1785 A1 from its modern nomenclature, is a faint parabolic comet that was observed several times by French astronomers, Charles Messier and Pierre Méchain, in January 1785.
Charles Messier measured the position of the cluster and included it as "M45" in his catalogue of comet-like objects, published in 1771. Along with the Orion Nebula and the Praesepe cluster, Messier's inclusion of the Pleiades has been noted as curious, as most of Messier's objects were much fainter and more easily confused with comets ...
The French astronomer Charles Messier discovered M87 in 1781, and cataloged it as a nebula. M87 is about 16.4 million parsecs (53 million light-years) from Earth and is the second-brightest galaxy within the northern Virgo Cluster, having many satellite galaxies. Unlike a disk-shaped spiral galaxy, M87 has no distinctive dust lanes.
