The Green Bank Telescope operated by the National Radio Astronomy Observatory is seen in Green Bank, West Virginia on October 29, 2014. The Green Bank Telescope, or GBT, is the world’s premiere single-dish radio telescope operating at meter to millimeter wavelengths. Its enormous 100-meter diameter collecting area, its unblocked aperture, and its excellent surface accuracy provide unprecedented sensitivity across the telescope's full 0.1 - 116 GHz (3.0m - 2.6mm) operating range. To protect the GBT from interference, a national quiet zone was established in 1958, where cell phones, Wifi, antennas, and other electronic devices are restricted. AFP PHOTO / Fabienne FAUR
