NGC 6644 is a bipolar planetary nebula located in the constellation Sagittarius.NGC 6644 was discovered by American astronomer Edward Charles Pickering in 1880. With an apparent visual magnitude of 10.7, a telescope with an aperture of at least 150 millimeters must be used to observe it.
M 1-42 is a planetary nebula located in the constellation of Sagittarius, ... The nebula has been nicknamed the "Eye of Sauron Nebula" due to its resemblance to the ...
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 ...
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.
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 .
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 .
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 location of NGC 3576 (circled in red) NGC 3576 is a bright emission nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carinae nebula. It is also approximately 100 light years across and 9000 light-years away from Earth. [3] It was discovered by John Frederick William Herschel on 16 March 1834. [4]
