Epoch (astronomy)

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.

IRAS

The Infrared Astronomical Satellite (IRAS) was the first-ever space-based observatory to perform a survey of the entire sky at infrared wavelengths.

Irregular galaxy

An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.

Light-year

A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances.

Lyon-Meudon Extragalactic Database

The Lyon-Meudon Extragalactic Database (LEDA) was a database of galaxies, created in 1983 at the Lyon Observatory, which was merged with Hypercat to become HyperLeda in 2000.

Metre per second

Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.

Morphological Catalogue of Galaxies

The Morphological Catalogue of Galaxies (MCG) or Morfologiceskij Katalog Galaktik, is a Russian catalogue of 30,642 galaxies compiled by Boris Vorontsov-Velyaminov and V. P. Arkhipova.

New General Catalogue

The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a well-known catalogue of deep-sky objects in astronomy compiled by John Louis Emil Dreyer in 1888, as a new version of John Herschel's Catalogue of Nebulae and Clusters of Stars.

Parsec

A parsec (symbol: pc) is a unit of length used to measure the astronomically large distances to objects outside the Solar System.

2MASS

The Two Micron All-Sky Survey (2MASS) was a survey of the whole sky in three infrared wavebands around 2 micrometres (μm): J (1.25 μm), H (1.65 μm), and Ks (2.17 μm).
