NGC 2264 is a star-forming region located in the constellation Monoceros. It is also known as the Cone Nebula due to its shape, which is formed by a dark, cone-shaped dust cloud that appears to be pointing towards a bright cluster of stars known as the Christmas Tree Cluster.

The Cone Nebula is a popular target for astronomical observation due to its striking shape and the bright young stars that can be found within it. The Christmas Tree Cluster, officially named NGC 2264, is an open cluster of stars located within the Cone Nebula. It is so named because it appears to resemble a Christmas tree with the bright stars of the cluster forming the shape of a tree and the dark nebula resembling the trunk and branches.
