Summary
| Description |
English: M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071. It is a reflection nebula which means that it contains very little ionized gas and merely reflects the light of the nearby stars and lies at an approximate distance of 1,600 light years from Earth. The nebula is located only about 2 degrees north and 1.5 degrees east of Alnitak, the easternmost star of Orion’s Belt. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Two early B-type 10th magnitude stars in M78, HD 38563A and HD 38563B, are responsible for illuminating the nebula’s dust clouds. A part of Barnards loop is visible in the upper right.
