Russell Croman Astrophotography  



The Cone Nebula

About This Photograph

Situated in the constellation Monoceros (the Unicorn), the tremendous light given off by the cluster of hot young stars both illuminates and is slowly eroding the vast cloud of gas and dust from which they were formed. A relatively dense lump of gas and dust blocks the light of the bright star at the center of the image, giving rise to the enigmatic column of dark gas and dust known as the Cone Nebula.

This is but a part of the larger nebula complex and star cluster seen in this photograph.
