| NGC2237.
The Rosette Nebula |
| Diffuse
nebula in Monoceros |
| It
is a prety large nebular complex that can be seen in the constellation
of Monoceros, surrounding the open cluster NGC2244 and it is a
collection of emission and dark nebulas and Bok globules. The cluster is a group of half a dozen stars that can be seen with naked eye in the winter milky way, but the nebula is difficult to see with a telescope due to its wide span. The stars of the cluster formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow in red (excited hidrogen). The Rosette Nebula spans about 100 light-years across and lies about 5000 light-years away from the Earth. |
