World’s largest radio telescope built in China

China has built world’s largest radio telescope nicknamed Tianyan (Heavenly Eye” or “The Eye of Heaven) or the five-hundred-metre aperture spherical radio telescope (FAST). It has started its operation and is part of China’s drive to become a science powerhouse. It is located in the Dawodang depression (vast natural crater), a natural basin in Pingtang County in the Guizhou Province,

Southwest China. Key Facts With its opening, the intensive testing phase of the telescope will begin. It will take nearly three years to calibrate the instruments of telescope to become fully operational. The facility is part of China’s drive to become a science powerhouse. It is an ambitious project of the National Astronomical Observatories of China. It is the world’s largest filled aperture (single dish) radio telescope and the second largest radio telescope after the Russian RATAN-600, which has a sparsely filled aperture. It is made up of 4,450 panels and has reflector as large as 30 football pitches. It has 500 meters diameter, giving it more sensitivity. It will be used to search for signs of intelligent life and to observe distant pulsars – tiny, rapidly spinning neutron stars believed to be the products of supernova explosions. It will be also used to study stellar radio emissions, gravitational waves and potentially signals from extraterrestrial civilizations. China’s best supercomputers the SkyEye-1 will be used to process the massive amounts of data supplied by FAST.
