2004年6月3日 · The Trifid Nebula, cataloged by astronomers as Messier 20 or NGC 6514, is a well-known region of star formation lying within our own Milky Way Galaxy. It is called the Trifid because the nebula is overlain by three bands of obscuring interstellar dust, giving it a trisected appearance as seen in small telescopes.

Trifid Nebula (Messier 20, NGC 6514) is a bright nebula located near the larger Lagoon Nebula in Sagittarius. M20 is composed of an emission nebula, reflection nebula, dark nebula, and a massive young open cluster.

Messier 20 (NGC 6514), also known as the Trifid Nebula, is a nebula w/cluster located in the constellation Sagittarius, in the Sagittarius Arm of the Milky Way Galaxy in the Local Group of galaxies. M20 is 4000 light years away from Earth. M20 is best viewed during late summer, is magnitude 6.3, and can be viewed with binoculars.

Trifid nebula (M20,NGC6514) is a emission/reflection nebula. It was discovered in 1764 by Charles Messier. It's location is RA (18:02.6), Dec (-23:02) and its distance is calculated 5.2 light years away. Its visual Brightness is 9.0. Its apparent dimensions measured in arcmins is 28.0. Trifid Nebula location is 18:02.6 (R.A.) and -23:02 (Dec.).

Trifid, M20, NGC 6514 The Trifid Nebula, M20 or NGC6514, is a familiar sight and an excellent example of an emission and reflection nebula. The red emission nebula contains a bright blue star cluster near its center: it glows red because the ultraviolet light of the stars ionizes the hydrogen gas, which then recombines and emits the ...

2004年6月3日 · This nebula, also known as Messier 20 and NGC 6514, lies within our own Milky Way Galaxy about 9,000 light-years (2,700 parsecs) from Earth, in the constellation Sagittarius. This new image from the Hubble Space Telescope offers a close-up view of the center of the Trifid Nebula, near the intersection of the dust bands, where a group of ...
