"The Trifid Nebula".
The Trifid Nebula, catalogued as Messier 20 and as NGC 6514, is an H II region located in Sagittarius. 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 trifid appearance. The Trifid Nebula is 7600 light years away from Earth.
