About this image


The Orion nebula or M42 is one of the brightest and closest nebulae in the night sky. It has also been the most studied and it contains areas of star forming regions and excellent structures formed by the stellar winds of the very young open cluster, the Trapezium. This image was produced with the light of Hydrogen, Oxygen, and Sulphur.
