Important resources for researching articles:
- The Astrophysics Data System Abstract Service - - This is a search engine that allows users to view the abstracts for virtually all professional astronomical articles published since 1900. Articles published before 1996 may be viewed by the general public. Articles published after 1996 may only be viewable to people at universities or research institutions, although the preprint versions of the articles are still viewable by everyone.
- The ArXiv.org E-Print Archive - This is a general preprint server that includes preprint (pre-publication) versions of many professionally-published articles. Note that these preprints should only be used if the article is not available from the ADS Abstract Service, as the preprint may not be the same as the final paper. Moreover, some papers appearing on ArXiv.org are never actually published.
- The NASA Exoplanet Archive - An online astronomical exoplanet and stellar catalog and data service that collates and cross-correlates astronomical data and information on exoplanets and their host stars and provides tools to work with these data. The archive serves important public data sets involved in the search for and characterization of extrasolar planets and their host stars, including stellar and exoplanet parameters and discovery/characterization data (such as published radial velocity curves, photometric light curves, images, and spectra).
- The NASA/IPAC Extragalactic Database (NED) - NED is a database search engine that contains useful information, including basic data (positions, magnitudes, and redshifts) for virtually all objects outside the Milky Way Galaxy. NED can also be used to look up references on specific objects.
- SIMBAD Astronomical Database - SIMBAD is a general-purpose database search engine that contains basic data on virtually all objects outside the Solar System. For extragalactic objects (objects outside the Milky Way Galaxy), this can be used as an alternative to NED (although data from NED is currently preferred for articles on galaxies).
- The Hubble European Space Agency Information Centre - Contains tons of public domain Hubble Space Telescope pictures and other graphics.
