Look up the position and details of astronomical objects by name. LookUP is a simple web service interface to a variety of astronomical name resolvers that should cover most astronomical objects but not spacecraft (their apparent position depends on the location of the observer).

LookUP is provided for free and is created by Stuart Lowe. If you make use of the service, we request that you attribute it to "LookUP", when space is very limited, or to "LookUP (operated by Stuart R. Lowe)" elsewhere and in papers. A link back to this site would be nice. If you make use of the object data, please attribute the service (e.g. Simbad, NED, SkyBot etc) where those data were found. In the XML output, this can be found within the <service> tag.

The iPhone App version was created by Alasdair Allan (University of Exeter).

Finally, this is all made possible through the use of the SIMBAD database (operated at CDS, Strasbourg, France), the NASA/IPAC Extragalactic Database (NED; operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration), the SkyBoT project (set up under the auspice of the French Ministry for National Education and CNRS), the Extrasolar Planets Encyclopedia (Jean Schneider, CNRS/LUTH - Paris Observatory), the Central Bureau for Astronomical Telegrams Supernovae List (IAU, Smithsonian Astrophysical Observatory), the Royal Astronomical Society of Canada Constellation List (Larry McNish), the SDSS SkyServer, the Minor Planet & Comet Ephemeris Service (IAU Minor Planet Center), the excellent WCSTools package (Jessica Mink, Smithsonian Astrophysical Observatory) and Yahoo's YQL (for the Wikipedia/Flickr images).

You won't find the Death Star in it.
