“Some strange signals have been found, but it’s hard to confirm their origins, because these signals do not repeat,” says Li Di, chief scientist at FAST, China’s Five-hundred-meter Aperture Spherical Radio Telescope, the world’s most sensitive listening device. “We look for not only television signals, but also atomic bomb signals. We’ll give full play to our imaginations when processing the signals,” Li states. “It’s a complete exploration, as we don’t know what an alien is like.”
