NASAIPAC Extragalactic Database - NED

edit
The NASAIPAC Extragalactic Database NED provides a multi-wavelength fusion of data for millions of objects outside the Milky Way galaxy. The astrophysical objects covered in NED include galaxies quasars and other active galactic nuclei AGNs gravitational lenses absorption line systemscomponents of galaxies such as supernovae HII regions star clusters and variable stars as well as unclassified sources from sky surveys at radio sub-millimeter infrared visual ultraviolet X-ray and gamma ray frequencies. Content and services include positions cross-identifications and statistical associations redshifts photometry and spectral energy distributions SEDs morphological classifications spectral classifications Galactic extinction along the line of sight FITS images links to distributed archive services as well as the Level 5 Knowledgebase... read more
