China’s Aperture Spherical Radio Telescope from Way, Way Up

Inside a forested crater in the limestone hills of Guizhou province sits the largest and most sensitive single‑dish radio telescope ever built. The Five‑hundred‑metre Aperture Spherical Radio Telescope surveys the sky for pulsars, interstellar molecules and signs of alien life. Even before construction was completed in 2016, it was attracting tourists, with hotels, a museum and a theme park nearby.
