Astronomical databases and archives
ADS Abstract Service Provided by the Astrophysics Data System at the CfA to search astronomy periodical abstracts
Cambridge Astronomical Survey Unit The APM facility, Carlsberg Meridian Telescope, and wide-field astronomy projects.
CADC: the Canadian Astronomy Data Centre A major international centre for data archives.
Double Star Library Catalogues and news of all types of binary and multiple systems, organized under the auspices of IAU Commission 26.
ESAC Science Data Centre Provides links to the data archives of all ESA science missions.
ESIS: the European Space Information System The ESIS project is a service to the Space Science community to provide access to scientific data, including catalogues, images and spectra from a wide range of ESA/non-ESA space missions. The ESIS Bibliographical Database combines the NASA Abstracts archive with SIMBAD references. A form-based interface allows you to search for bibliographic references in various ways.
HEASARC The High-Energy Astrophysics Science Archive Research Center
HISTORY OF MATHEMATICS - Astronomy Section (maintained by St Andrews University)
ING Data archives of the Isaac Newton Group of telescopes.
IRSA: the InfraRed Science Archive IRSA provides archiving and 'data mining' of infrared-astronomy (and submillimetre) catalogues, including IRAS, ISO, Spitzer (SIRTF), and 2MASS.
LEDAS: the LEicester Database and Archive Service LEDAS provides an on-line astronomical database service, and access to archival data from high-energy astrophysics missions.
MAST: the Multimission Archive at Space Telescope MAST supports a variety of astronomical data archives, with the primary focus on scientifically related data sets in the optical, ultraviolet, and near-infrared parts of the spectrum, including HST, IUE, EUVE, ASTRO & ROSAT.
Meetings A comprehensive hypertext list of international meetings, maintained by the CFHT library.
The National Cataloguing Unit Catalogues and archives papers of "contemporary" scientists, including some RAS luminaries, such as Sir Harold Jeffreys and Keith Runcorn.
NED The NASA/IPAC Extragalactic Database, including cross-identifications, positions, redshifts and basic data, plus bibliographic references.
NIST Physical Reference Data Includes physical constants, atomic and molecular spectroscopic data.
NSSDC NASA's National Space Science Data Center; includes the permanent archive for most NASA astrophysics data.
SIMBAD Astronomical Database SIMBAD provides basic data, cross-identifications and bibliography for astronomical objects beyond the Solar System.
SkyView SkyView is a virtual observatory on the internet. It can be used to generate images of the sky at wavelengths in all regimes from radio to gamma-ray using various sky surveys as input.
