The NASA/IPAC Extragalactic Database (NED) is a thematic, on-line research facility that supports scientists, educators, space missions, and observatories in planning, data analysis, discovery, and publication of research on extragalactic objects. NED’s ongoing mission is to provide a comprehensive and easy-to-use, multi-wavelength fusion of fundamental data for all known (cataloged and published) objects beyond the Milky Way. The contents and services span the entire spectrum from gamma rays through radio frequencies, and they are continuously updated to reflect the current literature and releases of large-scale sky survey catalogs. After a brief overview of NED’s primary features, we review current developments that are vastly extending the content and capabilities of NED for our modern era of research involving very large, multidimensional, multi-wavelength data sets in the context of an interoperable, global Virtual Observatory. We then illustrate how researchers can program various types of queries to NED and retrieve machine readable tabular output using modern programming/scripting languages, and review how developers around the world are integrating content from NED Web services into various applications. We close with a discussion of the challenges for managing increasingly large and diverse data sets while maintaining quality in NED operations, which are centered around the core activity of establishing cross-identifications and relating information from thousands of journal articles and catalogs containing observations of hundreds of millions of extragalactic objects and candidates.

Mazzarella, O. Pevunova, and M. Schmitz. NED-1D flourishes due to the dedication and enthusiasm of Ian Steer. Special thanks go to the IPAC System Group and E. Hacopians of the Spitzer Science Center for excellent work in upgrading and maintaining the NED computing infrastructure. H. Andernach, S. Atraya, J. Bennett, M. Bicay, M. Brouty, D. Daou, J. Jia, D.C. Kim, S. Kuhn, T. Patino, D. Schettini, B. Skiff, X. Wu and others contributed to NED over the years. NED is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with NASA. Recent developments for interoperability with the wider VO was partially supported by the U.S. National Virtual Observatory development project, which is funded by the National Science Foundation under cooperative agreement AST0122449 with The Johns Hopkins University. The imaging database, spectral database, and LEVEL 5 were initiated by grants from the NASA ADP and AISRP programs.
