About FAST

The Five-hundred-meter Aperture Spherical radio Telescope utilize the depression in the Karst region in Guizhou province as its site. It is the largest single aperture radio telescope in the world, with an area of about 30 football fields. FAST will keep its leading position for the upcoming 20 to 30 years. The innovative design along with the unprecedented site help it push the limiting aperture of about 100 m of a traditional telescope and create a new regime of large telescope construction.
