Explanation:
From afar, the whole thing looks like an
eagle.
A closer look at the
Eagle Nebula,
however, shows the
bright
region is actually a window into the center of a larger dark shell of
dust.
Through this window, a brightly-lit
workshop appears
where a whole open cluster
of stars is being formed.
In this cavity,
tall
pillars and
round globules of dark dust and cold
molecular gas
remain where stars are still forming.
Already visible are several young
bright blue stars
whose light and winds are burning away and pushing back the
remaining filaments
and walls of gas and dust.
The Eagle emission nebula,
tagged M16, lies about 6500
light years away, spans about 20 light-years,
and is visible with
binoculars
toward
the constellation of the Serpent
(Serpens).
This picture
involved
long and deep exposures and combined
three specific emitted colors emitted by
sulfur (colored as yellow),
hydrogen (red), and
oxygen (blue).
