NASA/IPAC Extragalactic Database (NED)

invisible.xbm invisible.xbm

The NASA/IPAC Extragalactic Database (NED) is an ongoing project, funded by NASA, to make data and literature on extragalactic objects available over computer networks. NED is an object-oriented database which contains extensive information for nearly 132,000 extragalactic objects taken from about major catalogs of galaxies, quasars, infrared and radio sources. NED provides positions, names, and other basic data (e.g. magnitude types, sizes and redshifts as well as bibliographic references and abstracts). Searches can be done by name, around a name, and on an astronomical position. NED contains a tutorial which guides the user through the retrieval process. Telnet to ipac.caltech.edu and log in as `ned'.
