Description

M17, also called the Swan or the Omega nebula, is located in the constellation Sagittarius, toward the center of the Milky Way about 6000 LY from earth. It is easily visible in binoculars. The red color is from emission of ionized hydrogen, with the brighter regions also showing starlight reflected by dust. The gas in this nebula is denser than most, containing the equivalent of 800 suns. In a few million years it should produce a conspicuous star cluster.
