Description

The Orion Nebula, also known as M42, is the nearest major star forming region to Earth at a distance of roughly 1,500 light years. It is easily visible to the naked eye from most latitudes as the middle star in Orion's sword/scabbard (below the belt when viewed from the northern hemisphere). It is thought to be about 24 light years across and has the mass of 2,000 suns. Many of the 2,800 or so stars that are contained within the open cluster of the Orion Nebula are obscured by gas and dust. The red colors in the image come from ionized hydrogen gas that fluoresces when electrons drop back onto their parent nuclei. The blue colors come from starlight that is scattered by dust and gas in the cloud; the process is the same one that makes our skies blue.

On the left of the image is the Running Man nebula, also known as Sh2-279, and is primarily a reflection nebula rather than an emission nebula. It lies at the same distance as the larger Orion Nebula and is part of the much larger Orion Molecular Cloud Complex. Together, these are two of the most photographed objects in the night sky.
