The Rosette Nebula C49The
Rosette Nebula (also known as
Caldwell 49) is an HII Region located near one end of a giant molecular cloud in the constellation Monoceros. The open star cluster NGC-2244
(Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
