Trifid Nebula
The Trifid Nebula (also known as M20 and NGC 6514) is an H II region at right ascension 18h 02.3m and declination -23° 02', located in Sagittarius. The nebula's name means "divided into three lobes".

The Trifid Nebula, M20, is probably best known for its three-lobed appearance. The dark areas are lanes of dark dust that obscure the nebula's light. This diffuse nebula is very large, and is located about 5,000 light-years from Earth.
The Trifid Nebula is found 1.5 degrees north of the Lagoon Nebula. M21 (NGC 6531) is a rather unspectacular open cluster 0.7 degrees NW of M20.
The Trifid Nebula, or Messier 20 (NGC 6514), is another region of star formation in Sagittarius. It contains a reddish emission nebula, a blue reflection nebula, a dark nebula, and an open cluster of stars.
The Trifid Nebula is a giant star-forming cloud of gas and dust located 5,400 light-years away in the constellation Sagittarius.

The Trifid Nebula, otherwise known as M20, is a place where new stars are forming. It has been called a "dark night revelation, even in modest apertures." An 8- to 10-inch telescope is needed to see the triple-lobed structure of the nebula.

About 1 1/3 degrees from the Lagoon Nebula we find the Trifid Nebula. This is also a dusty nebula which is also known as NGC 6514, or more simply, M20. It is about 60% dimmer than M8, and spans half a degree across the sky.
Next to the Lagoon Nebula on our sky (but closer to us in space) is the Trifid Nebula, so-called because of the dust lanes that trisect the H II region behind them.
The last of the three diffuse nebulae, M20, called Trifid Nebula, got its name from the three dust lanes, which divide the nebula. This structure can only be seen with large telescopes.

Just to the northwest, and at about the same distance, lies the Trifid Nebula, Messier 20, which is cut by dark, dusty lanes and that, like the Lagoon, is set within dark clouds that are actively birthing stars.
It is best viewed from the southern hemisphere during the months of May through August, but is visible from latitudes below about 50° N. It is about 5 degrees south of the Trifid Nebula, in the constellation Sagittarius.
The exact centre of the Galaxy is believed to be marked by a radio-emitting source that astronomers call Sagittarius A. There are many notable objects in Sagittarius, including the Lagoon Nebula and the Trifid Nebula, ...
