The Swedish National Facility for Radio Astronomy
Onsala Space Observatory, the Swedish National Facility for Radio Astronomy, provides scientists with equipment to study the Earth and the rest of the Universe. We operate several radio telescopes in Onsala, 45 km south of Göteborg, and take part in international projects. The observatory is a geodetic fundamental station. Examples of activities:
- The 20 and 25 m telescopes in Onsala: Studies of the birth and death of stars, and of molecules in the Milky Way and other galaxies.
- The LOFAR station in Onsala: One part of an international network of antennas for studies of, e.g., the early history of the Universe.
- VLBI: Telescopes in different countries are linked together for better resolution ("sharper images").
- APEX: Radio telescope in Chile for sub-millimetre waves. Research about everything from planets to the structure of the Universe.
- Odin: Satellite for studies of, e.g., the Earth's atmosphere and molecular clouds in the Milky Way.
- ALMA, e-VLBI, Herschel, SKA: Developing and using new radio astronomical facilities.
- Space geodesy: Radio telescopes (VLBI), satellites (GPS) and gravimeters are used to measure Earth's rotation, movements in Earth's crust, and water vapour in the atmosphere.
- Receiver development: Laboratories for development of sensitive radio receivers.
Onsala Space Observatory was founded in 1949 by professor Olof Rydbeck. The observatory is hosted by the Department of Space Earth and Environment at Chalmers University of Technology, and is operated on behalf of the Swedish Research Council.
