M20 Trifid Nebula

M20 Trifid Nebula

M20 (NGC6514), also known as the Triffid Nebula, lies in the direction of the Constellation Sagittarius embeded deeply within the Milky Way at a distance of approximately 5,200 Light-Years. Such nebulae are formed when a giant molecular cloud of neutral hydrogen gas collapses, giving birth to new stars within the cloud. The stars ionize the surrounding gas, giving it a pinkish-red glow, known as an emission nebula. The blue areas are from reflected star light in the outlying areas of the cloud. Neutral gas within the pinkish-red emission cloud are areas of remaining neutral hydrogen. Images with the Hubble telescope reveal lots of interesting features, including jets of material and evaporating gaseous globules powered by the intense radiation of the newly forming stars. There is evidence that supernovae explosions may be responsible for the some of the dark dust lanes. By using the infrared, the Spitzer telescope was able to detect 30 embryonic stars and 130 fully-formed stars not seen before.
