The Trifid Nebula, also known as Messier 20, is a nebula located in the constellation of Sagittarius, with a very close proximity to the Lagoon Nebula. The striking feature about this nebula is its trifurcated shape, formed by dark lanes of molecular clouds cutting through the pink hydrogen alpha region into three parts, hence its name. The trifid nebula is an intriguing object because it contains all the three types of nebula: Emission in the pink region, absorption in the dark lanes, and reflection in the blue region.
