This is a close up view of an interesting area inside the Rosette Nebula. NGC 2237 is a large, circular hydrogen region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster, NGC 2244, is closely associated with the nebulosity, the stars having been formed from the nebula's matter. The Nebula is about 100 light-years across and is about 5000 light-years away.
The image was created using the Hubble palette with SII, Ha and OIII data mapped to the red, green and blue channels, respectively. The color was further manipulated to create the blue and gold motif, made popular by the Hubble Imaging Team.
