> This photograph depicts a classified “listening station” deep in the forests of West Virginia. The station is located at the center of the “National Radio Quiet Zone,” a region of approximately 34,000 square kilometres in West Virginia and parts of Maryland. Within the Quiet Zone, radio transmissions are severely restricted: omnidirectional and high-powered transmissions (such as wireless internet devices and FM radio stations) are not permitted.

> The listening station, which forms part of the global ECHELON system, was designed in part to take advantage of a phenomenon called “moonbounce.” Moonbounce involves capturing communications and telemetry signals from around the world as they escape into space, hit the moon, and are reflected back towards Earth.

> The photograph is a long exposure under the full moon light.
