Description

The Trifid Nebula (M20 and NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85).
