Description
The Rosette Nebula (C 49 / lower left) is a large spherical H-alpha region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. It is associated with the open cluster NGC 2244 and lies about 5000 light-years from Earth.
The Cone Nebula (NGC 2264 / upper right) shares the same region of the sky as seen from Earth, but at about 2,700 light-years, it lies only about half as far away from Earth as Rosette Nebula. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264. The faint nebula is approximately seven light-years long.
