The Trifid Nebula, M20 in the
Messier Catalogue or NGC 6514, is a combination of an open star cluster and three different types of nebula in the constellation of Sagittarius.
The pink area shown in the image below is a Hydrogen II region emission nebula, the blue area is a reflection nebula. The dark nebula that appears to divide the emission nebula into three parts gives M20 its name the Trifid Nebula.
