Description

The Rosette Nebula is an emission nebula, a large star forming region located in the constellation Monoceros. The nebula is a large cloud of gas and dust that lies near a large molecular cloud and is closely associated with the open cluster NGC2244, whose stars were formed from the nebula’s matter in the last five million years.

The nebula is a region of intense star formation. The stellar winds from the young stars inside the nebula exert pressure on interstellar clouds and the compression leads to ongoing star forming activity in the nebula. The Rosette Nebula contains very hot young stars in its central region. The gas surrounding these stars has a temperature of 6 million kelvins and as a result the stars emit intense amounts of X-ray radiation. The nebula’s estimated mass is about 10,000 solar masses, which makes the Rosette one of the more massive emission nebulae known.

The nebula has several New General Catalogue designations: NGC2237 (cluster), NGC2238 (cluster), NGC2239 (obsolete name for NGC2244), and NGC2246 are all parts of the nebulous region, while NGC2244 is the bright open cluster located within the nebula.

In addition to the Rosette, the nebula SH2-280 in the upper left corner can be found in this image.
