Messier 28 or M28, also known as NGC 6626, is a globular cluster of stars in the center-west of Sagittarius.It was discovered by French astronomer Charles Messier in 1764. [11] [a] He briefly described it as a "nebula containing no star... round, seen with difficulty in 3 1 ⁄ 2-foot telescope; Diam 2′."
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 ...
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 ...
NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC 7335 , NGC 7336 , NGC 7337 and NGC 7340 , lie far in the background at distances of approximately 300–350 million light years.
NGC 3324 is an open cluster in the southern constellation Carina, located northwest of the Carina Nebula (NGC 3372) [3] [4] at a distance of 9,100 ly (2,800 pc) from Earth. [2] It is closely associated with the emission nebula IC 2599 , also known as Gum 31 . [ 5 ]
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]
RCW 49, also known as NGC 3247, is a H II region [1] nebula located 13,700 light years away. [2] Other designations for the RCW 49 region include NGC 3247 and G29 [3] and it is commonly known as the Whirling Dervish Nebula. [4] It is a dusty stellar nursery that contains more than 2,200 stars [2] and is about 300-400 light years across. [5]
