Effelsberg

With a diameter of 100 meters, the Radio Telescope Effelsberg (operated by the Max-Planck Institut für Radioastronomie in Bonn) is one of the largest fully steerable radio telescopes on earth. Since operations started in 1972, the technology has been continually improved (i.e. new surface for the antenna-dish, better reception of high-quality data, extremely low noise electronics) making it one of the most advanced modern telescopes worldwide.
