The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′. German-born astronomer William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2]
H II region: Soul Nebula: 330 ly (100 pc) [45] H II region: Heart Nebula: 330 ly (100 pc) [46] H II region: Has been named the “Heart nebula” because of its resemblance to a human heart. Henize 70 (N70 or DEM L301) [47] 300 ly (92 pc) [48] H II region: The N 70 Nebula, in the Large Magellanic Cloud has a shell structure and is really a ...
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]
The Gum catalog is an astronomical catalog of 84 emission nebulae in the southern sky. It was made by the Australian astronomer Colin Stanley Gum (1924-1960) at Mount Stromlo Observatory using wide field photography.

The nebula is part of the catalog of H-alpha stars and nebulae by Karl G. Henize, published in 1956. It is composed of the smaller nebulae N79A to N79E [ 1 ] From a CO survey it was however seen that the nebula is larger and contains N79-S, N79-W and N79-E. [ 2 ] These nebulae were described by Henize with other names, with N79-S being the ...
[5] [6] The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. [5] The star is one of the primary sources illuminating the nebula ...
Messier 77 (M77), also known as NGC 1068 or the Squid Galaxy, is a barred spiral galaxy in the constellation Cetus. It is about 47 million light-years (14 Mpc ) away from Earth, and was discovered by Pierre Méchain in 1780, who originally described it as a nebula.
