The Cone Nebula, the Christmas Tree Cluster, the Snowflake Cluster and the Fox Fur Nebula are all located in the Monoceros constellation. When Astronomers needed to name a new star cluster within NGC 2264 (the Christmas Tree Cluster), they chose the name “Snowflake Cluster” to fit a festive theme. The Snowflake Cluster can be seen above the brightest star in the nebula (near the center).
The Tornado is an unusual radio source near the center of the Milky Way Galaxy showing a number of remarkable filamentary structures influenced by the magnetic field. It is thought to be a supernova remnant, although the evidence is still inconclusive. Another unusual source is a cluster of bright, compact nebulae located in the lower right edge of the Tornado Nebula. Astronomers debate the nature of the relationship between the larger Tornado Nebula and the cluster of compact nebulae.
