NGC2264 - The Christmas Tree Cluster & Cone Nebula in Monoceros

 

This nebula and star cluster is located in the constellation of Monocerus, the unicorn. The Cone Nebula (seen at center right) and Christmas Tree Cluster star cluster bear the same designation: NGC 2264. The bright star at the center of the frame is S-Monocerotis. It acts as the base of the Christmas Tree Cluster.

William Hershel made this disovery in 1785. The region is a large star-forming region that lies approximately 26 thousand light years away and has a spance of 30 light years. Also visible just above S-Monocerotis is an area known as the Fox Fur Nebula (Sh2-273). Its shape is due to the stellar winds created by nearby stars.
