The European VLBI Network is an international collaboration of radio observatories that conducts very-long-baseline interferometry using telescopes in Europe and additional facilities in Asia, Africa, and elsewhere. By combining signals recorded at widely separated antennas, it functions like a radi...
The Very Long Baseline Array (VLBA) is a system of ten identical 25-meter radio antennas distributed across the United States and its territories, from Hawaii to the Virgin Islands. Operated by the National Radio Astronomy Observatory, the VLBA uses very-long-baseline interferometry (VLBI) to combin...
MIT Haystack Observatory is a multidisciplinary research facility located in Westford, Massachusetts, operated by the Massachusetts Institute of Technology. The observatory's primary instrument is a 37-meter radio telescope used for very long baseline interferometry (VLBI), radio astronomy, and geod...
Onsala Space Observatory, located on the west coast of Sweden near Gothenburg, serves as the country's national facility for radio astronomy. Operated by Chalmers University of Technology, the site is equipped with several key instruments, including a 25-meter and a 20-meter radio telescope. These f...
The Algonquin Radio Observatory (ARO) is a radio astronomy research facility located in Algonquin Provincial Park in Ontario, Canada. Its primary instrument is a 46-meter (150-foot) parabolic radio dish, which was commissioned in 1966 and was briefly the largest fully steerable antenna in the world....
The Hartebeesthoek Radio Astronomy Observatory (HartRAO) is a research facility located in South Africa that specializes in radio astronomy and space geodesy. Originally established in the 1960s as a NASA tracking station to support uncrewed lunar and planetary missions, it was converted into a scie...
The Medicina Radio Observatory is a major astrophysical facility located near Bologna, Italy. Operated by the National Institute for Astrophysics (INAF), the site features two distinct primary instruments: a 32-meter parabolic antenna and the Northern Cross, a massive T-shaped transit interferometer...
Inaugurated in 1988 in Sicily, Italy, the Noto Radio Observatory is a 32-meter dish facility used for radio astronomy, geodynamics, and deep-space spacecraft tracking.
