M78 is the messier objects, and M78 is a reflection nebula located in Orion. M78 is a part of the large nebula region formed by M42 and M43. Distance 1600 light years, about 4 light years. 1780 was found. Nebulae are forming young stars. In addition, this nebula is the star of Altman set by the Japanese special drama Altman.

M78 is the brightest diffuse reflection nebula among NGC 2064, NGC 2067 and NGC 207 1. This group belongs to Orion B molecular cloud complex, which is about 1 350 light years away from the earth. M78 looks like a patch with two stars, such as apparent magnitude 10 and apparent magnitude 1 1, so it is easy to find.

These two stars are both B-type stars, numbered HD 38563 A and HD 38563 B. M78 can only be seen by reflecting their light through dust clouds. Under the infrared ray, we can see that there are a group of stars in M78, and the molecular gas in the nebula has been split into continuous clumps due to gravity. In M78, there are about 45 T-shaped Taurus variables and about 65,438+07 young stars called Herbig-Harrow objects.
