The night sky in SVG, PDF and PNG formats. These objects, numbered M104 to M110, are now accepted by astronomers as "official" Messier objects.StarCharter is a command-line tool for producing vector-graphics charts of On several different occasions between 19, astronomers and historians discovered evidence of another 7 deep-sky objects that were observed either by Messier or his friend and assistant, Pierre Mechain, shortly after the final version was published. Many of these objects he actually discovered himself. Over the next 7 years he updated the catalogue and published the final version in 1781, containing 103 objects. The first version of his catalogue contained 45 objects and was published in 1774 in the journal of the French Academy of Sciences in Paris. These fuzzy "comet" like objects hindered his searches so he catalogued them in order to avoid them in future. When searching for comets he was frustrated by fixed objects that looked like comets in the night sky but actually weren't. Messier was a comet hunter who was born in Badonviller, France on June 26, 1730. It was compiled in the 18th century by Charles Messier. It consists of 110 deep sky objects, including open and globular star clusters, galaxies, nebulae, an asterism, a double star and even a supernova remnant. The Messier Catalogue is a famous catalogue in Astronomy.
