NGC 2264 is a region that holds the Cone Nebula, a dark nebula and a star-forming region in the Northern region of the Unicorn constellation, and the Christmas Tree open cluster, a group of very young stars that lies “above” the Cone Nebula, towards the South of the constellation. The Christmas Tree cluster is an active star-forming region. With these two main objects, we can also see the Snowflake Cluster in the middle of NGC 2264. It is also a star-forming region full of very young stars.
