Messier Catalogue

Charles Messier, a French astronomer, during the mid-18th century began observing with his telescope a number of objects that were visible from France. Although Messier was a “comet hunter”, in scanning space he was attracted by some particular “objects” that did not look like stars. Some objects had already been “recorded” by other astronomers, but Messier decided to start noting them by indicating their position and describing what he was able to see. Many notes made by Messier, in our day, are very superficial, sometimes quite inaccurate or completely wrong. Some globular clusters were noted as “nebula” but it is more than forgivable, considering the instruments of the time.

What must be said is that Charles Messier created what was the first Catalog of non-stellar objects for that time. In 1774 he published the first edition of the Catalog des Nébuleuses et des Amas d ’Étoiles (Catalog of Nebulae and Star Clusters) which contained only 45 objects. The final version was published in 1781 and contained the 110 objects of the current catalog. The objects in the catalog are now known and indicated with the initials M followed by the number (Ex. M1)

A brief note on the M102 object in its catalog. Object M102 has been cataloged as a “Galaxy” but there are many disputes about this object. It is thought that it may be an “oversight” of Messier and that it may be a duplicate of the Pinwheel Galaxy, already cataloged as M101, but other hypotheses indicate that it was the “Spindle Galaxy” or some nearby galaxies.

However, the most accredited theory is that it is the “Spindle Galaxy” – NGC 5866 as it is only about 5 degrees from the galaxy M101 and Messier’s maps had a 5o grid. It is very likely that Messier noted the wrong position.
