Observatories

An Observatory is a building housing an astronomical telescope or other sceintific equipment that is operated from the ground an observes astronomical, meteorological, or other natural phenomena.

Herschel Space Observatory
The Herschel Space Observatory's mission has been designed to unveil a face of the early Universe that has remained hidden until now. Thanks to its ability to detect radiation at far infrared and sub-millimetre wavelengths, Herschel will be able to observe dust obscured and cold objects that are invisible to other telescopes.
Keck Observatory
W. M. Keck Observatory operates the two biggest, and most scientifically productive telescopes in the world on the summit of Mauna Kea, Hawaii.
Solar & Heliospheric Observatory
SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind.
United States Naval Observatory
The United States Naval Observatory (USNO) provides a wide range of astronomical data and products, and serves as the official source of time for the U.S. Department of Defense and a standard of time for the entire United States.
