The Trifid Nebula, also known as M20 or NGC 6514, is located in constellation Sagittarius at an uncertain distance between 2000 and 7000 light-years from the Earth. This very beautiful object is an unusual combination of an open cluster of stars, an emission nebula (the red portion), a reflection nebula (the blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifid appearance; these are also known as Barnard 85).
