    Caption: The Eagle Nebula (M16) from Kitt Peak National Observatory, Kitt Peak, Arizona.

    Features:

    1. The Eagle Nebula is a star forming region about 1.740(130) kps (5,700(400) ly) away in constellation Serpens.

    2. 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.

    3. 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

    4. The 3 Pillars of Creation from the famous Hubble Space Telescope (HST) image are in the center.

    5. 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.

    6. 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.

    7. 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.
