Lyon-Meudon Extragalactic Database
Appearance

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. It was a new version of the older Principal Galaxies Catalogue that was published in 1989.[2] It originally contained information on more than 60 parameters for about 100,000 galaxies, and now contains information on over 3 million celestial objects, of which about 1.5 million are galaxies. The database allows astronomers around the world access to its information.
