Today I reprocessed some old data I had for Messier 16.
Messier 16 (M16), the famous Eagle Nebula, is a star-forming nebula with a young open star cluster located in Serpens.
M16 lies near the borders with the constellations Sagittarius and Scutum. The nebula is best known for the Pillars of Creation region, three large pillars of gas famously photographed by Hubble in 1995.
Also known as the Star Queen Nebula, M16 lies at a distance of 7,000 light years from Earth and has an apparent magnitude of 6.0. The cluster’s designation in the New General Catalogue is NGC 6611, while the nebula is referred to as IC 4703.
The Eagle Nebula occupies an area 70 by 55 light years in size, or 30 arc minutes of the sky, while the open cluster has a radius of 15 light years, corresponding to 7 arc minutes in angular diameter.
The name Eagle comes from the nebula’s shape, which is said to resemble an eagle with outstretched wings. American astronomer Robert Burnham, Jr. introduced the name Star Queen Nebula because the nebula’s central pillar reminded him of a silhouette of the Star Queen. (MESSIER OBJECTS)
