Radio Quiet Zone on Radio 4

Every day next week [starting Monday 18th May] on Radio 4 at 12.04: Welcome to the quiet zone.

13,000 square miles of radio quiet in the US – no mobile phones – around Greenbank, the world’s largest fully steerable telescope, to protect the radio telescope from harmful interference.

In anticipation of the Radio 4 programme, you might be interested to see details of other Radio Quiet Zones around the European telescopes, including the Lovell telescope at Jodrell Bank Observatory:-
