The Eagle Nebula is an emission nebula contained with a young (1-2 million years) open cluster of ~460 stars that is ~6,500 light-years away in the constellation Serpens. Its name derives from its shape that is thought to resemble an eagle. It is the subject of the famous "Pillars of Creation" photograph by the Hubble Space Telescope that shows pillars of star-forming gas and dust within the nebula.
