NGC 1788 is a reflection nebula in the constellation of Orion. It is rather sharply defined on its southwest perimeter where it is flanked by the dark nebula known as LDN 1616 (or Lynds 1616). LDN 1616 is apparently part of NGC 1788. The brightest involved star is 10th magnitude and lies in the northwest sector.
NGC 2467, nicknamed the "Skull and Crossbones Nebula", [3] is a star-forming region whose appearance has occasionally also been likened to that of a colorful mandrill. It includes areas where large clouds of hydrogen gas incubate new stars. [ 4 ]
When John Louis Emil Dreyer compiled the New General Catalogue of Nebulae and Clusters of Stars he used William Herschel's earlier observations that described two objects in a "double nebula", giving the northern most the designation NGC 2443 and the southernmost most the designation NGC 2442. Herschel's later observations noted that the two ...
Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year. [4] M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071.
IC 11, Sh2-184, [3] Sharpless 184, [1] LBN 616, LBN 123.17-06.28, Pacman Nebula See also: Lists of nebulae NGC 281 , IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way 's Perseus Spiral Arm .
Jewel Bug Nebula, [citation needed] Gummy Bear Nebula [5] See also: Lists of nebulae NGC 7027, also known as the Jewel Bug Nebula or the Magic Carpet Nebula , [ 6 ] is a very young and dense planetary nebula [ 7 ] located around 3,000 light-years (920 parsecs ) from Earth in the constellation Cygnus .
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
NGC 6445, also known as the Little Gem Nebula or Box Nebula, is a planetary nebula in the constellation Sagittarius. It was discovered by William Herschel on May 28, 1786. [ 6 ] The distance of NGC 6445 is estimated to be slightly more than 1,000 parsecs based on the parallax measured by Gaia , which was measured at 0.9740 ± 0.3151 mas.
