Explore the biggest radio telescope in the world

The five-hundred-meter Aperture Spherical radio Telescope (FAST), located in a karst depression in Guizhou, is the world's largest single-dish radio telescope, with a receiving area equivalent to 30 football fields.

As a big fan of space exploration, British vlogger Oli Barrett set off on a trip to explore FAST. He was astonished by this massive telescope and touched by the story of the chief engineer of FAST, Nan Rendong.
