NGC2244 is actually the open cluster found in the center of this large emission nebula. The open cluster is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.The radiation from the young stars excite the hydrogen, oxygen, and sulfur atoms in the nebula, causing them to emit radiation and the emission nebula we see. Distance is estimated to be 5200 light years away.
