     The above picture is of the constellation Monoceros, star forming region NGC 2264.  It is roughly 2700 light-years in distance.  It mixes red emission nebulae and blue reflection nebulae.  This picture specifically includes the Fox Fur Nebula, the Cone Nebula, and S Mon (a young dwarf star which gives the photo a blue glow).  The red color in the photo and the Cone Nebula is produced by hydrogen gas.
