Subj : Daily APOD Report To : All From : Ben Ritchey Date : Mon Oct 15 2018 06:00:05 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 October 15 [2] M16: In and Around the Eagle Nebula Image Credit & Copyright: Andrew Klinger [3] Explanation: From afar, the whole thing looks like an Eagle [4] . A closer look at the Eagle Nebula [5] , however, shows the bright region [6] is actually a window into the center of a larger dark shell of dust [7] . Through this window, a brightly-lit workshop appears [8] where a whole open cluster [9] of stars is being formed. In this cavity tall pillars [10] and round globules [11] of dark dust and cold molecular gas [12] remain where stars are still forming. Already visible are several young bright blue stars [13] whose light and winds are burning away and pushing back the remaining filaments [14] and walls of gas and dust. The Eagle emission nebula [15] , tagged M16, lies about 6500 light years [16] away, spans about 20 light-years, and is visible with binoculars [17] toward the constellation [18] of the Serpent ( Serpens [19] ). This picture [20] involved over 25 hours of imaging and combines three specific emitted colors emitted by sulfur [21] (colored as red), hydrogen [22] (yellow), and oxygen [23] (blue).
