European Southern Observatory
ESO operates a suite of the world's most advanced ground-based astronomical telescopes located at the La Silla Paranal Observatory in the Atacama desert in Chile

HAO : High Altitude Observatory
The High Altitude Observatory (HAO), through its collaboration with scientists and scientific organizations around the world is recognized as a premier authority on Sun and Sun-Earth studies

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

Kitt Peak National Observatory
Kitt Peak National Observatory (KPNO), part of the National Optical Astronomy Observatory (NOAO), supports the most diverse collection of astronomical observatories on Earth for nighttime optical and infrared astronomy and daytime study of the Sun

Lick Observatory
California observatory near and part of the University of California, Santa Cruz

NSO : National Solar Observatory
The mission of the National Solar Observatory is to advance knowledge of the Sun, both as an astronomical object and as the dominant external influence on Earth, by providing forefront observational opportunities to the research community

University of Hawaii 2.2-meter Telescope
Near the summit of Mauna Kea

U.S. Naval Observatory
USNO is the preeminent authority in the areas of Precise Time and Astrometry, and distributes Earth Orientation parameters and other Astronomical Data required for accurate navigation and fundamental astronomy.

W.M. Keck Observatory

Current Hubble Location
Where is the Hubble Space Telescope right now?

Herschel Space Observatory (formerly FIRST)
The fourth cornerstone mission in the European Space Agency (ESA) science programme. It will perform imaging photometry and spectroscopy in the far infrared and submillimetre part of the spectrum, covering approximately the 55-672 µm range

Hubble Project
The Hubble Space Telescope (HST) is a large, space-based observatory which has revolutionized astronomy by providing unprecedented deep and clear views of the Universe, ranging from our own solar system to extremely remote fledgling galaxies forming not long after the Big Bang 13.7 billion years ago

Hubble Discoveries, Pictures and photo archives, press releases, the telescope, and astronomy

INTEGRAL: International Gamma-Ray Astrophysics Laboratory)
The International Gamma-Ray Astrophysics Laboratory is the second medium-sized mission of ESA's Horizon 2000 Science Programme. Fine spectroscopy and fine imaging of celestial gamma-ray sources in the energy range 15 keV to 10 MeV with concurrent source monitoring in the X-ray (3-35 keV) and optical (V-band, 550 nm) energy ranges

Spitzer Space Telescope
Spitzer will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space between wavelengths of 3 and 180 microns
