Visiting the radio telescopes in Humain (Belgium)
During the weekend of September 9 and 10, it was possible to visit the radio telescopes in Humain (Belgium). It was the first time since the site was opened in 1953 that a visit was possible. The station is used by the Royal Observatory of Belgium . A solar interferometer of 48 radio telescopes was build in the 1960s. The telescopes are not used anymore since 2001. All telescopes are have a diameter of 4 meter and are located at a height of 293 above sea level. A few larger telescopes are still in use at the site. Enjoy the pictures!
