The Rosette Nebula / NGC 2244 in Hubble Palette
If you are creative, you can see both a rose and a hobbit skull within the image.
The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open 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.
