Messier 20 (M20), also known as the Trifid Nebula, is a famous star-forming region located in the constellation Sagittarius; located in a star-rich arm of our galaxy (The Milky Way).

The nebula’s designation in the New General Catalogue is NGC 6514. The name Trifid refers to its three-lobed appearance. Messier 20 consists of several different objects: an emission nebula (the magenta region), a reflection nebula (the cyan region) , a dark nebula (the trifurcation lines); and an open star cluster.

The dark nebula, catalogued as Barnard 85, consists of dust clouds that absorb and block light from the bright objects behind them. It is responsible for the apparent gaps in the larger emission nebula that give M20 its trifurcated look.
