NASA/IPAC Extragalactic Database http://ned.ipac.caltech.edu/classic NED News Featured Updates March 2014 (N24.2.4) Preview release of a new user interface Explore galaxy environments via radial velocity constrained cone searches 40 million objects from the GALEX All Sky Catalog with NED cross-IDs 471 million objects from the 2MASS Point Source Catalog (cone searches) 1 million new objects with redshifts(5.2 million total) NED is embarking on a major transformation:We invite you to preview a new interface providing a drop-down menu and a form to search for objects By Name directly on the landing page(future homepage).A new Near Position search option includes catalog sources that are undergoing integration into NED.All users should read about these significant changes.Further streamlining of the interface,including consolidation of search forms,will be released incrementally with new content and evolving functionality.
