The Messier objects are a group of deep sky objects catalogued by the French astronomer Charles Messier in the late 18th century.
Messier’s Catalogue des Nébuleuses et des Amas d’Étoiles (Catalogue of Nebulae and Star Clusters) is a collection of deep sky objects (galaxies, nebulae, star clusters) and other astronomical objects (asterisms, binary stars) that were visible with binoculars and telescopes at the time.
Messier compiled the list between 1758 and 1782. His original goal was to list the objects that were frequently confused for comets. He was a comet hunter, which was a popular activity among 18th century astronomers, and this led him to create the first comprehensive list of deep sky objects that frustrated his search.
The Italian astronomer Giovanni Hodierna had compiled a similar catalogue of astronomical objects, about 40 of them, and published it in 1654, but his work had no major impact and Messier was likely unaware of it.
The Messier objects are popular targets among amateur astronomers because they are relatively bright and easy to find and observe in small telescopes. Messier himself used a relatively small refractor telescope (4 inch, or 100 mm) for his observations. In the early spring, all the objects can be seen over the course of a single night.
Messier made his observations from Paris, France, which is why his catalogue doesn’t include prominent deep sky objects that can only be seen from the southern hemisphere, such as the Large and Small Magellanic Clouds.
The southernmost object on Messier’s list is Messier 7, the Ptolemy Cluster, an open cluster in Scorpius constellation, found at declination -34°47’34’’. At magnitude 3.3, the cluster is bright enough to be seen from the northern hemisphere in the summer months.
Messier’s list includes almost all the best examples of different types of deep sky objects – galaxies, open clusters, globular clusters, planetary nebulae, and diffuse nebulae – that can be observed from Europe. Most Messier objects are among the nearest examples of their class to Earth and can be seen in great detail with larger instruments, which makes them popular targets for study among professional astronomers as well.
Messier’s catalogue was first published in “Mémoires de l’Academie“, the journal of the French Academy of Sciences in Paris in 1774, and the final version came out in 1781, in Connaissance des temps for 1784, an official astronomical annual publication in France.
The original catalogue included 45 deep sky objects, and the 1781 version had 103.
Today’s versions of Messier’s catalogue contain 110 objects, as they include objects that were observed by Messier and his colleague Pierre Méchain after the catalogue was published. The final seven Messier objects – M104 to M110 – were added by astronomers and historians between 1921 and 1966 after discovering evidence that the objects were observed either by Messier or Méchain.
Messier 104 was added by the French astronomer and author Nicolas Camille Flammarion in 1921, objects M105 to M107 were added by the Canadian astronomer Helen Sawyer Hogg in 1947, M108 and M109 were added by the American astronomer Owen Gingerich in 1960, and the last one, M110, was added by the Welsh astronomer Kenneth Glyn Jones in 1967.
