Astronomical Resources on the Web

Internet Starting Points

Astronomical Internet Resources from STScI, AURA, Goddard

The Star*s Family of Astronomy and Related Resources
StarWorlds (organizations, institutions, associations, companies, etc.)
StarHeads (more than 5000 personal WWW pages of individuals)
StarBits (abbreviations, acronyms, contractions, symbols, etc.)

Science:Astronomy in the Yahoo database.
An educational resource, including a good list of astronomers' web pages.
Griffith Observatory's Web Star Awards
The Gaileo Project
He lived 400 years ago, but he still has a very extensive web site.
Patrick Shopbell's Astronomy Links
A subject-sorted guide to astronomical information available over the Internet.
The Universe Today
A daily digest of space exploration news, with links to articles from various media on the net. Sometimes the reporters get the story first, but often you can read the original press releases on the newsgroup.
Encyclopedia of Astronomy and Astrophysics
This joint project of Nature and the Institute of Physics requires a subscription to see the full text of most articles, but it has one free one per week and access to brief entries and "Breaking News".

SETI (Search for Extraterrestrial Intelligence)

NASA Exoplanet Archive
The NASA Exoplanet Science Institute (NExScI) runs this NASA-funded service that provides exoplanet and stellar host properties and Kepler candidate properties presented in interactive tables, including centroiding information from the Kepler pipeline.
UC Berkeley SETI Program, University of California Search for ExtraTerrestrial Intelligence
Breakthrough Listen is taking data with the Green Bank Telescope (the world's largest steerable radio telescope), the Parkes radio telescope in Australia, and the Automated Planet Finder (a robotic optical telescope equipped with cutting edge spectrograph technology).
SERENDIP (Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations) is an ongoing scientific research effort aimed at detecting radio signals from extraterrestrial civilizations. This site describes the SERENDIP project and discusses the status of the search.
SETI@home is a grand experiment to harness the spare power of hundreds of thousands of Internet-connected computers in the Search for Extra-Terrestrial Intelligence (SETI) by spreading around the analysis of data from Arecibo.
SETI League
International grass-roots organization dedicated to privatizing the electromagnetic Search for Extra-Terrestrial Intelligence.
Motto: "SETI is a science, not simply a screensaver!"
International Academy of Astronautics SETI Permanent Study Group
Originators of the Rio Scale, designed to quantify the impact of any announcement regarding evidence of extraterrestrial inteligence.
SETI Institute
Information about scientific research in the general field of Life in the Universe with an emphasis on the Search for Extraterrestrial Intelligence.
