The French astronomer Charles Messier was a c
hunter that kept discovering objects he thoug
initially were comets but turned out to not be co
upon further inspection.
Messier catalogued around 110 of those previo
supposed comets which remain somewhat usef
modern day astronomy, albeit limited as all t
observations were done only in France.
Within the Messier catalogue, all 110 entries ha

The New General Catalogue of Nebula an
Clusters of Stars (NGC) are a list of galaxies,
clusters, and emission nebulae and absorptio
nebulae catalogued by number.
Objects are prefixed with ‘NGC’ (e.g., the
Nebula is NGC 1952).
