China Sky Eye, the world’s largest single-dish radio telescope, is now fully operational
China’s Five-hundred-meter Aperture Spherical Radio Telescope, known as FAST, is the world’s most sensitive listening device. The single-dish radio telescope is made of 4,450 individual panels that scan the sky, detecting the universe’s whispers and shouts. It’s cradled in a natural Earth depression the size of 30 soccer fields. It has more than twice the collecting area of the world’s previous largest radio telescope, the 305-meter dish in Arecibo, Puerto Rico. With construction completed in 2016, FAST has undergone rigorous testing and has one more hurdle before it’s considered fully operational.
