Green Bank, West Virginia, USA. 15th Dec, 2013. Employee Dave Curry stands in front of the telescope at the National Radio Astronomy Observatory (NRAO) in Green Bank, West Virginia, USA, 15 December 2013. There is a Radio Quiet Zone in the area so that the world's largest steerable radio telescope can pick up the faintest of signals, therefore no mobile telephones or wifi are allowed.
