ISO 639 is a standardized nomenclature used to classify all known languages. Each language is assigned a 2-letter (639-1) and 3-letter (639-2 and 639-3), lowercase abbreviation, amended in later versions of the nomenclature.

The first attempts at systematic catalogues of galaxies were made in the 1960s the Catalogue of Galaxies and Clusters of Galaxies listing 29,418 galaxies and galaxy clusters, and with the Morphological Catalogue of Galaxies, a putatively complete list of galaxies with photographic magnitude above 15 comprising 30,642 items. In the 1980s, the Lyons Groups of Galaxies listed 485 galaxy groups with 3,933 member galaxies.
This is a list of the brightest individual stars in determined by their average apparent magnitudes in the visible spectrum as seen from Earth. This is not the same as a list of the brightest stars as seen with the naked eye, as close binary or multiple star systems will appear as a single star with an apparent magnitude greater than their individual components, e.g. the binary system Rigel Kentaurus has an apparent magnitude of -0.27, but the brightest individual star is Alpha Centauri A with the apparent magnitude as listed here of -0.01.
