NGC 2264 - The Cone Nebula in Monoceros


Copyright 2007 Hap Griffin

The extraordinary Cone Nebula is a 7 light-year long column of cold molecular hydrogen and dust extending from a much larger field of the same.   It is an active region of star birth, with the three small stars at its peak having only relatively recently becoming luminous.  The large cloud of glowing hydrogen in the upper portion of this photograph is the root of the "Foxfur Nebula".

NGC 2264 lies at a distance of 2600 light years.
