Explanation:
An eerie blue glow and ominous columns of
dark dust highlight M78, a bright
reflection nebula
in the constellation of Orion.
The
dust
not only absorbs light, but also reflects the
light of several bright blue stars that
formed recently in the nebula.
The same type of scattering that colors the
daytime sky further enhances the blue color.
M78
is about five
light-years across and visible through a small telescope.
M78
appears above only as it was 1600 years ago,
however, because that is how long it takes
light to go from
there
to here.
M78
belongs to the larger
Orion Molecular Cloud Complex
that contains the
Great Nebula in Orion and the
Horsehead Nebula.
