The Barnard's Loop is bright in northern region and can be taken clearer than southern part. And this image shows you the extraordinary dimmed gaseous matter is distributed between the Great Orion Nebula (M42) and the outer shell of the Loop in southern region. It's considered that the Barnard's Loop is a spreading hydrogen gas by a supernova explosion occurred around between the Great Orion Nebula and the Horse head Nebula about a million years ago. And maybe the dimmed nebulosities may be left matter in a process of the diffusion of "Blast". The Barnard's Loop has a catalogue number of Sh2-276, but it's a number of only northern regions, the southern remaining part has no identifying numbers. |
