The '''Orion Nebula''' (also known as '''Messier 42'''), is the brightest star forming, diffuse nebula in the sky, situated south of the belt of [[Orion]].  Having an apparent magnitude of 3, the nebula can be seen by the unaided eye in moderately dark skies. It is estimated to be some 24 light years across and is some 1,344±20 light years from Earth<ref>http://arxiv.org/abs/0902.3913</ref>.  The Orion Nebula itself is only part of a vastly larger star forming nebular region called the '''Orion Molecular Cloud Complex'''.
