Rosette Nebula

The Rosette Nebula is an emission nebula that lies about 5000 light years away in the constellation Monoceros. At the centre of the nebula lies the star cluster NGC 2244 which comprises massive O and B type stars that drive the stellar winds that have all but cleared the central region of gas and dust. These stars also provide the energy that excites the ring shaped emission cloud known as the Rosette Nebula.
