LDN 1622: The Boogeyman Nebula
Explanation: To some, the dark shape looks like a mythical
boogeyman. Scientifically, 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, the brighter reflection nebula
vdB 62 is more easily seen just above and to the right of center in the
featured image. 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 2-
degree wide field of view would span about 60 light-years.
Young stars do
lie hidden within the dark expanse and have been
revealed in
Spitzer Space Telescope infrared images.

Where is the boogeyman? Under your bed?

Ha ha, no! The boogeyman is in the armpit of Orion, below Betelgeuse.
Phew, the smell!!!

A large proportion of the YSO's in the LDN 1622 show characteristics of HH-objects. Could it be that the HH-objects simply mark a phase in star formation - I mean from every star? Or develops only certain kind of star jets, which become visible as HH-objects?

According to my pareidolia, she looks like the silhouette of MM in a mink coat in Men Prefer Blondes, with a microphone in hand, singing and dancing.

I prefer seeing this nebula north up.
