NGC 2264, also known as the Cone Nebula and the Christmas Tree Cluster. It is located in the constellation Monoceros.
It is an emission nebula with a star cluster at it's center. The stars in the cluster excite the hydrogen gas around it giving the red glow.
Just below and a little to the left of the central star cluster is a cone shaped gas projection, pointing up, that gives the Cone Nebula it's distinctive name. (NASA; TheSky, Software Bisque)
