The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745-46. Its name derives from its shape which is resemblant of an eagle. It is the subject of the famous "Pillars of Creation" photograph by the Hubble Space Telescope, which shows pillars of star-forming gas and dust within the nebula.
