China finishes construction of world's largest radio telescope

(Chinese Academy of Sciences Headquarters) After more than five years of construction, the world's largest single-dish radio telescope is finally getting ready to open its eye. On July 3, 2016, with the installation of the last of its 4,450 reflecting panels -- equivalent to the size of 30 soccer fields -- the Five-hundred-meter Aperture Spherical radio Telescope is counting down to seeing its first light in two to three months' time.
