NASA/IPAC Extragalactic Database   Latest Updates to NED and Level 5 Knowledgebase
New Query Redshift-Independent Distances by Object Name
New Redshift-Independent Distances in query reports
New Query volumes of space around objects in query reports
New Improved query reports including Index and SED preview
New 450,000 object Associations between SDSS and other surveys  		NED
NED will be unavailable intermittently 9AM - 2PM Pacific time (1700 - 2200 UTC) on Saturday, November 7th due to network maintenance at IPAC.
Ongoing upgrades to the user interface include changes to the HTML query reports. Automated queries should use XML (VOTable) output. Details
