M16 - EAGLE NEBULA

Messier 16, the Eagle Nebula, is a spectacular emission nebula and star-forming region in the constellation Serpens, located approximately 7,000 light-years from Earth. The nebula spans roughly 70 by 55 light-years and is home to the young open cluster NGC 6611, whose hot, massive stars illuminate and sculpt the surrounding gas and dust. M16 achieved worldwide fame in 1995 when the Hubble Space Telescope captured the iconic "Pillars of Creation" image, showing towering columns of interstellar gas and dust where new stars are actively forming. These pillars, the tallest of which extends about 4 light-years in length, are being photoevaporated by the intense ultraviolet radiation from the cluster's hottest stars, a process that simultaneously triggers and destroys star formation. The cluster NGC 6611 is very young, only about 1 to 2 million years old, and contains several stars more than 80 times the mass of our Sun that will live brief but brilliant lives before ending as supernovae. M16 was first discovered by Philippe Loys de Cheseaux around 1745, who noted the star cluster, while Messier cataloged the surrounding nebulosity in 1764. For amateur astronomers, the nebula is visible in binoculars as a hazy patch, while the star cluster is easy to resolve with any telescope. Seeing the nebulosity itself, including hints of the pillars, requires a telescope of at least 6 to 8 inches with a narrowband or OIII filter under dark skies. The Eagle Nebula is a premier astrophotography target, revealing intricate detail in long-exposure images.

Spans approximately 70 by 55 light-years at a distance of 7,000 light-years, containing the young cluster NGC 6611 with stars up to 80 solar masses.
