OBJECT DESCRIPTION AND IMAGE SESSION

NGC 2014 (Henize 55) is a cluster of hot, young stars, almost hidden in the brightest part of the nebula. The energetic ultraviolet light from these stars is absorbed by hydrogen and produces the distinctive red glow from an enormous distance around the cluster. As well as radiating strongly in ultraviolet light (a result of their high temperature) massive young stars also produce vigorous stellar winds. Eventually they will disperse the hydrogen around them, evacuating a bubble-like nebula. To the top of the main cluster a single star has begun this process, creating a strange hollow shape. (*)
