Everything about Messier 78 totally explained
The nebula
Messier 78 (also known as
M 78 or
NGC 2068) is a
reflection nebula in the
constellation Orion. It was discovered by
Pierre Méchain in
1780 and included by
Charles Messier in his catalog of
comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the
Orion Molecular Cloud Complex and is about 1,600
light years distant from
Earth. M78 is easily found in small
telescopes as a hazy patch and involves two
stars of 10th
magnitude. These two stars,
HD 38563A and
HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.
About 45
variable stars of the
T Tauri type, young stars still in the process of formation as well as some 17
Herbig-Haro objects are known in M78.
