The Trifid Nebula (catalogued as Messier 20 or M20 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).
M20 lies at a distance of about 5,200 light-years.
