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.
