**M78: Reflecting Blue in a Sea of Red**

Explanation:
In the vast Orion Molecular Cloud complex,
several bright blue nebulas are particularly apparent.

Pictured here in the center are two of the most prominent
reflection nebulas -
dust clouds lit by the
reflecting light of bright embedded
stars.

The more famous nebula is
M78,
in the image center, cataloged over 200 years ago.

To its upper left is the lesser known
NGC 2071.

Astronomers continue to
study these
reflection nebulas to
better understand how interior stars form.

The overall red glow is from diffuse
hydrogen gas
that covers much of the
Orion complex
that spans much of the
constellation of Orion.

Nearby in the
greater complex,
which lies about 1,500
light years away, are the
Orion Nebula,
the Horsehead Nebula, and
Barnard's Loop --
partially seen here as the white band on the upper left.
