Caption: The Eagle Nebula (M16)
from
Kitt Peak National Observatory,
Kitt Peak,
Arizona.
Features:
- The Eagle Nebula is
a star forming region about
1.740(130) kps (5,700(400) ly)
away in constellation
Serpens.
- It is called the Eagle Nebula
because someone thought it looked like an eagle---and
NOT
because it is in
constellation
Aquila
which it is NOT.
- The image is a mosaic in false color from
emission line images:
Hα
(green),
oxygen [O III]
(blue),
sulfur [S II]
(red).
Hα
should be
red/pink
and maybe [O III] should be green to be
true color
- The 3
Pillars of Creation
from the famous
Hubble Space Telescope (HST) image
are in the center.
- Note that one has bright emission gas clouds heated by newly
formed OB stars that are evaporating the
interstellar dust,
in the dark dusty clouds where
star formation continues.
- Without some sky map,
it's hard to tell which stars are
OB stars
in the Eagle Nebula
and which are foreground stars
which are bright because they
are relatively close to us.
- The group of bright stars that the
Pillars of Creation are pointing
to are probably OB stars
in the Eagle Nebula
because they are a dense group associated with
Eagle nebula---this is
unlikely to be an accident.
