Radio Telescopes
The Lovell Telescope was designed in 1945 to be fully steerable, so that it could be pointed to any part of the sky, right down to the horizon. More than 40 years after it was conceived, there are only two fully steerable instruments larger than the Lovell Telescope.
Sir Bernard Lovell, the creator of the giant 76-m (250ft) radio telescope needed a quiet observing site away from the radio interference of the city and was directed to a place called Jodrell Bank, 20 miles south of Manchester. Since the summer of 1957 it has been quietly probing the depths of space.
