M16: Inside the Eagle Nebula
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 over 12 hours of imaging and combines three specific emitted colors emitted by
sulfur (colored as red),
hydrogen (yellow), and
oxygen (blue).
