Nan Rendong, chief scientist of the FAST project with the National Astronomical Observatory, Chinese Academy of Sciences, told

“A radio telescope is like a sensitive ear, listening to tell meaningful radio messages from white noise in the universe. It is like identifying the sound of cicadas in a thunderstorm.

There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope.”
