This huge radio telescope near the village of Effelsberg in Germany is operated by the Max-Planck-Institut für Radioastronomie in Bonn. With its diameter of 100 metres it is the world's second largest fully-steerable radio telescope after the Green Bank Telescope in the United States. To avoid interference with artificial radio signals, the telescope was built in a valley.
