ARECIBO Observatory: This is the Radio Telescope where [email protected] downloads its data from.
CAMBRIDGE University, Institute Of Astronomy: Much observational work centres around the use by staff of large telescopes abroad and in space to study quasars, galaxies and the chemical constitution of stars.
Griffith Observatory: This Observatory is a non-profit educational institution whose purpose is to provide information on astronomy and related sciences to the public.
Paranal Observatory: The Very Large Telescope (VLT) at Cerro Paranal is ESO’s premier site for observations in the visible and infrared. All four unit telescopes of 8.2m diameter are individually in operation. The VLT offers also the possibility of combining coherently the light from the four UTs to work as an interferometer, the Very Large Telescope Interferometer (VLTI), with its own suite of instruments, ultimately providing imagery at the milli arcsecond level as well as astrometry at 10 micro arcsecond precision.
SOHO — Exploring The Sun: The SOHO (Solar & Heliospheric Observatory) project is being carried out by the European Space Agency (ESA) and the US National Aeronautics and Space Administration (NASA) as a cooperative effort between the two agencies in the framework of the Solar Terrestrial Science Program (STSP) comprising SOHO and CLUSTER, and the International Solar – Terrestrial Physics Program (ISTP), with Geotail (ISAS-Japan), Wind and Polar.
Hubble’s Main Site: All Hubble pictures and news, from the latest discoveries to the earliest images. Coast through cosmic images; browse their archive by date, subject or release type.
The Hubble Deep Field: The Hubble Deep Field (HDF) is a Director’s Discretionary program on HST to image a typical field at high galactic latitude in four wavelength passbands as deeply as reasonably possible. In order to optimize observing in the time available, a field in the northern continuous viewing zone (CVZ) was selected and images were taken for 10 consecutive days, or approximately 150 orbits. (henceforth referred to as the Hubble Deep Field North, or HDF-N)
The Hubble Deep Field — South: A second Hubble Deep Field campaign was carried out between late September and October of 1998. The rationale for undertaking a second deep field campaign followed from the wealth of information that has come out of HDF-N, and from the desire to provide a point of focus for similar studies of the distant universe from southern-hemisphere facilities.
