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
combines three specific emitted colors and was taken with the 0.9-meter
telescope on Kitt Peak, Arizona, USA.
