         Object NGC2237
         Comment The Rosette Nebula (aka NGC2237, Caldwell 49) is a large, spherical (circular in appearance), HII region residing in the constellation Monoceros. The colourful open star cluster NGC2244 at the center of the nebula is closely associated with the surrounding nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 50 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the red emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses. Source: Wikipedia
