April 10, 2012: A Fox Fur, a Unicorn, and a Christmas Tree
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.
