Czech Republic Becomes ESO Member
Jan 2007
Officials from the Czech Republic signed an agreement in Prague last month making the country the 13th member of the European Southern Observatory (ESO) and the first from central and eastern Europe. Other ESO members are Belgium, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Astronomy in the Czech Republic is shared between the Astronomical Institute of the Academy of Sciences, which operates a 2-m optical telescope and a 10-m radio telescope, and several universities. ESO, with headquarters in Garching, Germany, provides research facilities to European astronomers and astrophysicists. It operates three observational sites in the Chilean Atacama desert: The Very Large Telescope on the mountain Paranal, several medium-sized optical telescopes at La Silla and the new submillimeter telescope APEX at Llano de Chajnantor.

The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
radio telescope
An instrument designed to collect naturally formed extraterrestrial electromagnetic radiation within the radio frequency range of the spectrum in amounts sufficient to be measured.
An afocal optical device made up of lenses or mirrors, usually with a magnification greater than unity, that renders distant objects more distinct, by enlarging their images on the retina.
