The Trifid Nebula (M20, NGC 6514) is an emission nebula in Sagittarius that lies less than two degrees from the Lagoon Nebula. Discovered by French comet-hunter Charles Messier , it is located between 2,000 and 9,000 light-years from Earth and has a diameter of approximately 50 light-years.
The Omega Nebula is an H II region in the constellation Sagittarius.It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier catalogued it in 1764. It is by some of the richest starfields of the Milky Way, figuring in the northern two-thirds of Sagittarius.
The Small Sagittarius Star Cloud (also known as Messier 24 and IC 4715) is a star cloud in the constellation of Sagittarius approximately 600 light years wide, which was catalogued by Charles Messier in 1764. [4] The stars, clusters and other objects comprising M24 are part of the Sagittarius or Sagittarius-Carina arms of the Milky Way galaxy ...
The Little Gem Nebula or NGC 6818 is a planetary nebula located in the constellation of Sagittarius. It has magnitude 10 and oval diameter of 15 to 22 arcseconds with a 15th magnitude central star. It was discovered by William Herschel in 1787. NGC 6818 is located in the constellation of Sagittarius (The Archer), roughly 6000 light-years away ...
Star cluster NGC 6520 and dark nebula Barnard 86 within the Large Sagittarius Star Cloud Superimposed upon the Large Sagittarius Star Cloud is the bright open cluster NGC 6520 . Close by to the west is the small dark nebula Barnard 86, a Bok globule described by Edward Emerson Barnard as “a drop of ink on the luminous sky”.
Messier 22 or M22, also known as NGC 6656 or the Great Sagittarius Cluster, is an elliptical globular cluster of stars in the constellation Sagittarius, near the Galactic bulge region. It is one of the brightest globulars visible in the night sky.
NGC 6530 is a young [8] open cluster of stars in the southern constellation of Sagittarius, located some 4,300 light years from the Sun. [3] It exists within the H II region known as the Lagoon Nebula, or Messier 8, [9] and spans an angular diameter of 14.0′. [5]
The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and has an H II region .
