The Trifid Nebula

The Trifid Nebula in Sagittarius

Discovered by Charles Messier in 1764. The Trifid Nebula Messier 20 (M20, NGC 6514) in Sagittarius is a remarkable and beautiful object as it consists of both a conspicuous emission nebula and a remarkable reflection nebula component. Charles Messier discovered this object on June 5, 1764, and described it as a cluster of stars of 8th to 9th magnitude, enveloped in nebulosity, where the remark on nebulosity follows only after the description of nearby M21, and includes that object. The Trifid Nebula M20 is famous for its three-lobed appearance.
