NGC 6565 (also known as ESO 456-70) is a planetary nebula in the constellation of Sagittarius. The object formed when a star ejected its outer layers during the late stages of its evolution . The remnant core of the star, a white dwarf , is emitting vast amounts of ultraviolet radiation that ionizes , or excites, the gas surrounding it, making ...
NGC 6590 is a reflection nebula in the constellation of Sagittarius. [2] This nebula is near the similar reflection nebula NGC 6589 . Both nebulas are flanked by red emission nebula IC 1284 .
NGC 6520 is an open cluster of stars in the southern constellation of Sagittarius, [5] about 4° to the east of the Galactic Center. [3] With an apparent visual magnitude of 7.6 and an angular size of 6.0′, it can be viewed with binoculars or a small telescope. Just to the west of this cluster is the dark nebula Barnard 86, dubbed the Ink ...
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 .
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”.
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 apparent size of the nebula is 0.8'3 or 0.79'4 (0.795 ± 0.005'), which, taking into account the distance calculations, equates to an actual size of 1, 26 ± 0.26 al. Observations show the expanding CO shell is pretty much continuously distributed around the minor axis waist and the nebula is tilted to the plane of the sky. The shell is ...
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.
