The Eagle Nebula (also known as Messier Object 16, M16 or NGC 6611), perhaps one of the most famous and easily recognized space objects, is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745-46. It is associated with a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7,000 light years distant. The brightest star in the nebula has an apparent magnitude of 8.24, easily visible with good binoculars. In astronomy, an epoch is a moment in time for which celestial coordinates or orbital elements are specified. ... Equatorial Coordinates Right ascension (abbrev. ...

Understanding of processes inside the nebula was greatly improved by 1995 Hubble images. Small dark areas are believed to be protostars. They are found aplenty only in this nebula. The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble for his discovery of galaxies outside the Milky Way and his creation of Hubbles Law, which calculates the rate at which the universe is expanding. ... Protostar is a period after clouds of hydrogen, helium and dust begin to contract and before the star reaches the main sequence. ...
