The
M78 Nebulosity Complex
Reflection
Nebula in Orion
Uploaded 1/17/05
There
are few reflection nebulosities in the sky as bright and exciting
as M78. This 8th magnitude object is 7x8 arcminutes in size,
and lies in a region of space with a very high dust and gas content.
The blue portion in the middle of this image is caused by the
reflection of the light of the two bright stars in its interior
- known as "The Eyes". Around its periphery, dust that
is not illuminated that is in front of the blue parts causes
a more brownish or reddish coloration. To the upper right of
M78 separated by the dark bay is NGC2067 also known by its shape
as the "Hand Saw Nebula". Down below it a small bright
patch is NGC2064, and below it the small nebula is the newly
formed "McNeil's Nebula". |
