The famous Trifid Nebula is catalogued as Messier 20. "Its name means divided into three lobes" This target shows four different classes of deep - sky objects in one: star clusters, emission nebula (red hues}, reflection nebula (blue hues), and dark nebula (brown features; also designated barnard 85). It lies 5,200 light years away in Sagittarius. The Trifid Nebula is a star forming region in Scutum spiral arm of the Milky Way.

The most massive star that has formed in the region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars. So named for the dark bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future.
