A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. [6] The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. [7]
Planetary nebulae are observed in more distant galaxies, yielding useful information about their chemical abundances. Starting from the 1990s, Hubble Space Telescope images revealed that many planetary nebulae have extremely complex and varied morphologies. About one-fifth are roughly spherical, but the majority are not spherically symmetric.

It is also the brightest patch of nebulosity in the sky. [12] [13] [14] Small Magellanic Cloud (NGC 292) 2.7 200 kly (61 kpc) Tucana: Visible only from the southern hemisphere. [12] [15] Andromeda Galaxy (M31, NGC 224) 3.4 2.5 Mly (770 kpc) Andromeda: Once called the Great Andromeda Nebula, it is situated in the Andromeda constellation. [12] [16]
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies , star clusters and emission nebulae .
