On May 12, 1971, the opening ceremony took place at the site of the telescope, about one year later, on August 1, 1972, the Effelsberg radio telescope became fully operational.
Over the past five decades, a multitude of successful observations of the universe in radio waves have been made with the telescope, from our cosmic neighborhood in the Milky Way to very distant galaxies. Since then, a steady flow of technical upgrades of the telescope and its detector equipment are being made ensure that it is still one of the most powerful radio telescopes on Earth. The 100-m telescope plays a central role in the scientific work of the institute.
On April 1, 2021, a special stamp will be issued to mark the 50th birthday of the telescope.
