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 NGC 2244, whose stars were formed from the nebula’s matter in the last five million years.
The Rosette (or Rosetta) Nebula’s appearance in optical light resembles a rose flower or the rosette, the stylized flower design used in sculptural objects since ancient times, and the nebula was named after the design.
