M 20 The Trifid Nebula

20 or also known as NGC 6514 The Trifid Nebula is a well known region of  a star formation that is within our own Milky Way Galaxy. It was first observed by LeGentile in 1747 and rediscovered by Messier in June 1764. It received the name, by John Herschel, The Trifid, because the nebula is layered by three bands of murky interstellar dust, giving it the distinct three layered appearance as seen through telescopes. The Trifid is about 9,000 light years from Earth according to Hubble news releases and is about 10 to 13 light years across.The Trifid Nebula is in the direction of the constellation Sagittarius.
These images offer a close-up view of the center of the Trifid Nebula, near the intersection of the dust bands, where a group of recently formed, massive, bright stars are easily visible. These stars, which are classified as the hottest and bluest types of stars called type "O," are releasing ultraviolet radiation that radically influences the makeup and evolution of the surrounding nebula. Many astronomers studying nebulae like the Trifid are focusing their research on the ways that waves of star formation move through such regions.
