Database Contents

Tabular summaries of NED's current holdings are presented here. Graphic summaries are presented here.

References and Object Pointers

  • 1,176,297 new object links (pointers) to 3,248 new references
  • This release completes the results of cross-matching 471 million 2MASS Point Source Catalog (Skrutskie, M. F. et al. 2006AJ....131.1163S) sources with the contents of NED. 90% are new objects to NED and 10% have new cross-identifications with prior NED objects. This release includes the fusion of their J, H, Ks photometric data into object SEDs.
    For further information, please see 2MASS PSC holdings

  • 31 spectra from High molecular gas fractions in normal massive star-forming galaxies in the young Universe (Tacconi et al. 2010Natur.463..781T)
  • 51 spectra from The Nuclear Near-Infrared Spectral Properties of Nearby Galaxies (Mason et al 2015ApJS..217...13M)
  • 929 spectra from The COSMOS Active Galactic Nucleus Spectroscopic Survey. I. XMM-Newton Counterparts (Trump et al 2009ApJ...696.1195T)


  • 64 images from High molecular gas fractions in normal massive star-forming galaxies in the young Universe (Tacconi et al. 2010Natur.463..781T)
  • 20 images from V, R, I and H{alpha} photometry of circumnuclear star-forming regions in four galaxies with different levels of nuclear activity (Angeles et al. 2000MNRAS.311..120D)

June 2018 Release - The New Interface of NED

(Latest Revision: 22 Jun 2018)

The NED team is pleased to present a new user interface! The original web interface is being phased out and replaced with a modern, streamlined approach that simplifies and consolidates query forms, and provides interactive tables with linked graphics in the results.

Featured upgrades include:

  • A single search box on the main screen lets you easily search for objects by entering an object name, an object name or coordinates with a search radius, or a refcode. Image searches are also supported (click the ? icon by the search box for examples.)
  • Information for a single object is presented in a modern, convenient way:
    • A new Overview page summarizes key quantities, as available
    • Detailed data in different categories are organized in tabs
    • Integration of the IPAC Firefly toolkit provides interactive tables (including sorting, filtering, data downloads) and linked graphics
    • FITS images can be viewed in your browser using the IPAC Firefly image viewer (replaces the Aladin Java applet)
    • Documentation has been updated and re-organized (see Information in the main menu bar above)
  • Modernized forms for the calculators (under Tools in the menu bar): coordinate transforms, Galactic extinction, and velocity corrections
  • References now link to the new ADS interface
  • New API to query the NED Object Directory using the VO Table Access Protocol (TAP)

Some familiar NED features are not yet integrated into the new interface: Search Objects by IAU Name, Search Objects by Classifications, Build Data Table from Input List, Search References by Object Name, the Galaxy Environment tool, and Level 5. These will be included in upcoming releases, and meanwhile they remain available in the 'Classic Services' menu option (above). Please refer to the Known Issues page for more information.

We welcome your feedback and comments.
