Onsala Space Observatory is the Swedish National Facility for Radio Astronomy. It was founded in 1949. The observatory is hosted by Department of Radio and Space Science at Chalmers University of Technology, and is operated on behalf of the Swedish Research Council. The space observatory is located in Onsala, situated 45 km south of Göteborg, on the Swedish west coast.

Onsala Space Observatory provides scientists with equipment to study the Earth and the rest of the Universe. It operates two radio telescopes in Onsala, 20 and 25 meters. The telescopes are principally used for radioastronomical observations.

Onsala Space Observatory also serves as a data centre for the Odin satellite and in the planning of the scientific operations of the mission.  The Observatory is also a partner in the newly constructed Apex telescope, the Atacama Pathfinder Experiment, on Llano Chajnantor at an altitude of 5000 m in the Chilean Andes, and is building and installing several of the millimetre/sub-millimetre wave receivers. Additionally, Onsala is heavily involved in the Atacama Large Millimetre Array (Alma) and staff are working on various aspects of this unique European-US collaborative venture.
