Explanation:
The silhouette of an intriguing
dark nebula
inhabits
this cosmic scene.
Lynds' Dark Nebula
(LDN)
1622 appears against a faint
background of glowing hydrogen gas only visible in long telescopic
exposures of the region.
In contrast, a brighter reflection nebula,
vdB 62,
is more easily seen just above the dusty dark nebula.
LDN 1622 lies near the plane of our Milky Way Galaxy,
close on the sky to
Barnard's Loop,
a large cloud surrounding the rich
complex of emission nebulae found in the Belt and Sword
of Orion.
With swept-back outlines, the obscuring dust of LDN 1622 is thought
to lie at a similar distance, perhaps 1,500 light-years away.
At that distance, this 3 degree wide field of view
would span about 100 light-years.
Young
stars do lie hidden within the dark expanse and have been
revealed in Spitzer Space telescope
infrared
images.
Still, the
foreboding
visual appearance of LDN 1622
inspires its popular name,
the Boogeyman Nebula.
