The Trifid Nebula M20

Charles Messier discovered on June 5, 1764. It is combination of an open cluster of stars; an emission nebula, a reflection nebula and a dark nebula all three in one.

This Nebula is a star-forming region in the Scutum spiral arm of the Milky Way. It is approximately 5000 ly away from Earth and It have an apparent magnitude of 6.3.

It has been a subject of an investigation by astronomers using the Hubble Space Telescope in 1997, using filters that isolate emission from hydrogen atoms, ionized sulfur atoms, and doubly ionized oxygen atom. The images were combined into a false-color composite picture to suggest how the nebula might look to the eye.
