Eagle Nebula (M16) Observation Details
M16 Daily Motion
M16 will be visible until October, 29, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

Where is M16 right now?
M16 is located in the constellation Serpens2, at right ascension 18h 18m 48s" and declination -13° 48' 25s. At the current time, it is above the horizon at an altitude of 33 degrees toward the south-southeast from your location, with an apparent magnitude of 6.00.M16 - Eagle Nebula
The Eagle Nebula (M16) is an emission nebula located in the constellation Serpens. It was discovered by Jean-Philippe de Chéseaux in 1745-46 and later included in Messier's catalog in 1764. M16 is best known for the Pillars of Creation, a region of active star formation made famous by the Hubble Space Telescope.
The nebula spans about 70 light-years across and is illuminated by a cluster of young, hot stars known as NGC 6611. The Eagle Nebula is approximately 7,000 light-years away from Earth and has an apparent magnitude of 6.0, making it visible with binoculars or a small telescope.
