This nebula was discovered by the French astronomer Antoine Darquier de Pellepoix in January 1779, who reported that it was "...as large as Jupiter and resembles a planet which is fading." Later the same month, fellow French astronomer Charles Messier independently found the same nebula while searching for comets.
