World's largest radio telescope starts operating in China

September 26, 2016

The world's largest radio telescope began operating in southwestern China Sunday, a project which Beijing says will help humanity search for alien life. 

The Five-hundred-metre Aperture Spherical Radio Telescope (FAST), nestled between hills in the mountainous region of Guizhou, began working around noon.

Built at a cost of 1.2 billion yuan ($180 million), the telescope dwarfs the Arecibo Observatory in Puerto Rico as the world's largest radio telescope, with a reflector as large as 30 football fields, it said.
