NASA/IPAC Extragalactic Database  
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.
