Trifid Nebula, M20, NGC 6514

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764. Its name means ‘divided into three lobes’. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent ‘gaps’ within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

Messier 20 and 21

Image Credit & Copyright: Lorand Fenyes

The beautiful Trifid Nebula, also known as Messier 20, is easy to find with a small telescope in the nebula rich constellation Sagittarius. About 5,000 light-years away, the colorful study in cosmic contrastsshares this well-composed, nearly 1 degree wide field with open star cluster Messier 21 (top right). Trisected by dust lanes the Trifid itself is about 40 light-years across and a mere 300,000 years old. That makes it one of the youngest star forming regions in our sky, with newborn and embryonic stars embedded in its natal dust and gas clouds. Estimates of the distance to open star cluster M21 are similar to M20’s, but though they share this gorgeous telescopic skyscape there is no apparent connection between the two. In fact, M21’s stars are much older, about 8 million years old.

Trifid Nebula

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius.
The Trifid Nebula was the 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.
The close-up images show a dense cloud of dust and gas, which is a stellar nursery full of embryonic stars. This cloud is about8 light-years away from the nebula’s central star. A stellar jet protrudes from the head of the cloud and is about 0.75 ly long. The jet’s source is a young stellar object deep within the cloud. Jets are the exhaust gasses of star formation. Radiation from the nebula’s central star makes the jet glow.

M8 and M20

The Lagoon (down) and Trifid (up) nebulae are two very famous nebulae in Sagittarius, and both nebulae can be glimpsed with the naked eye (from a dark site), and they are easy to see with binoculars.

M8 and M20 – Lagoon and Trifid Nebulae

If you are in dark skies and can see the Milky Way streaming up from the horizon, you may notice a black area with two little fuzz balls in it that look like puffs of steam. If you are in suburbs or cities, you may notice just a fuzzy star above the spout. The fuzzy star or fuzz balls are the Lagoon and Trifid nebulae, or Messier Objects 8 and 20. You are seeing two star-forming regions toward the heart of our galaxy.

The Trifid is a little dimmer than the Lagoon. Trifid got its name because in photographs it has three distinct lobes. The Lagoon got its moniker because it looks like a round pool just outside the ocean of the Milky Way.

The Trifid Nebula

Also known as M20, this photogenic nebula is visible with good binoculars towards the constellation of Sagittarius. The energetic processes of star formation create not only the colors but the chaos. The red-glowing gas results from high-energy starlight striking interstellar hydrogen gas. The dark dust filaments that lace M20 were created in the atmospheres of cool giant stars and in the debris from supernovae explosions. The light from M20 we see today left perhaps 3,000 years ago.
