Barnard's loop

Barnard's Loop is an emission nebula in the constellation of Orion. It is part of a giant molecular cloud which also contains the Horsehead Nebulae and Orion nebula. The loop takes the form of a large arc centred approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop.
