This “out-of-this-world” Christmas Tree Cluster (NGC 2264) is a young triangular shaped open cluster of about 40 stars embedded in the northeastern corner of the constellation of Monoceros (the Unicorn). This image of the Christmas Tree Cluster is from NASA’s Spitzer Space Telescope. http://annesastronomynews.com/photo-gallery-ii/nebulae-clouds/the-christmas-tree-cluster-ngc-2264/
