| Description |
The brighter portions of the Rosette Nebula have
been assigned the designators NGC2237, NGC2238, NGC2239, and NGC2246.
In the center of the nebula lies the young (4 million years old) open
cluster NGC2244. The intense ultraviolet light from the cluster's
brightest stars are clearing a hole around them, and they will
eventually cause the dissipation of the entire nebula. |
