Messier 78 - Reflection Nebula
Messier 78, also known as NGC 2068, is a reflection nebula
in the constellation Orion. It is the brightest diffuse
reflection nebula in a group that includes NGC 2064, NGC 2067,
and NGC 2071, all part of the Orion B molecular cloud complex.
Located approximately 1,350 light-years from Earth, Messier 78
is visible in small telescopes as a hazy patch illuminated by
two B-type stars, HD 38563 A and HD 38563 B, of 10th and 11th
magnitude. It is a popular target for amateur astronomers, who
have given it the common name: Casper the Friendly Ghost Nebula.
Discovered by Pierre Méchain in 1780, Messier 78 was included in
Charles Messier's catalog of comet-like objects that are not comets,
that same year.
