SETI – Search For Extraterrestrial Intelligence

SETIStars – Help bring the Allen Telescope Array back online and continuously working by making a donation. The SETI program was shut down earlier this year (2011) due to budget cuts.

SETI Institute – The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.

SETI@Home – SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.

The SETI League – The international grass-roots organization dedicated to privatizing the electromagnetic Search for Extra-Terrestrial Intelligence. Together, fifteen hundred members in five dozen countries on all seven continents are keeping alive the quest for our cosmic companions.

Deep Sky

Black Holes and Neutron Stars – Understanding the nature of black holes and neutron stars can lead to a better understanding of how our Universe works.

Messier Marathon – Messier Marathon is a term describing the attempt to find as many Messier objects as possible in one night.

NGC/IC Project – The NGC/IC Project is a collaborative effort between professional and amateur astronomers working together to correctly identify all of the original NGC and IC objects.

Astronomical Databases

LookUP – An online tool from the Jodrell Bank Centre for Astrophysics that allows you to call up the positions and images of a huge number of objects from professional sky surveys all over the world as well as Flickr.

SIMBAD Astronomical Database – A powerful tool for finding out more about an object in the night sky. Search for any object by name, cataloge number, or RA and Dec. The result tells you wnat the object is and where to find it and provides a links to an image and related scientific papers. – Provides access to different sky surveys. Scroll and zoom around the whole sky and switch between many of the most famous surveys.

Space Telescopes and Missions

HubbleSite NewsCenter – The complete collection of every Hubble Space Telescope news release and its supporting materials, along with tools and resources designed to further your knowledge of astronomy.

Hubble Space Telescope (ESA) – The European home for the NASA/ESA Hubble Space Telescope.

James Webb Space Telescope – The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2013. JWST will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy.

New Horizons – New Horizons is designed to help us understand worlds at the edge of our solar system by making the first reconnaissance of Pluto and Charon – a “double planet” and the last planet in our solar system to be visited by spacecraft. Then, as part of an extended mission, New Horizons would visit one or more objects in the Kuiper Belt region beyond Neptune.

Space Science Telescope Institute – Home to planning, scheduling, and public outreach activities for the Hubble Space Telescope (HST). Data archive and distribution services for the HST and other missions are also provided by STScI.

STEREO Mission – STEREO consists of two space-based observatories – one ahead of Earth in its orbit, the other trailing behind. With this new pair of viewpoints, scientist will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space (in 3D).


Bradford Robotic Observatory The Bradford Robotic Telescope is 46cm and totally autonomous. located high on the moors in West Yorkshire, England. The telescope decides when the conditions are good enough to make observations of the sky by itself.

Dunsink Observatory – Site of the oldest scientific institution in Ireland, Dunsink Observatory is situated on a hill 8km northwest of Dublin’s city centre.

European Southern Observatory – A European organisation for astronomical research comprising eight member countries which operates astronomical observatories in Chile.

Gemini Observatory – The Gemini Observatory consists of twin 8-meter optical/infrared telescopes located on two of the best sites on our planet for observing the universe. Together these telescopes can access the entire sky.

Joint Astronomy Centre – Website coordinating information about the James Clerk Maxwell Submillimetre Telescope and the United Kingdom Infrared Telescope (UKIRT).

Large Binocular Telescope Observatory – The goal of the LBT project is to construct a binocular telescope consisting of two 8.4-meter mirrors on a common mount. This telescope will be equivalent in light-gathering power to a single 11.8 meter instrument.

Paranal (Very Large Telescope) Observatory – The Paranal Observatory comprises four 8 meter Unit Telescopes, a comprehensive first generation Instrumental Package for their 12 focii, as well as a combined focus for Interferometry. The observatory is located on Cerro Paranal, in the Atacama desert in northern Chile.

SkyView Virtual Observatory – SkyView is a Virtual Observatory on the Net generating images of any part of the sky at wavelengths in all regimes from Radio to Gamma-Ray.

SLOOH – SLOOH is a robotic observatory on the Canary Islands. Members can join observing missions or reserve observing time on the telescopes.
