This past September, China put on the "ear phones" and flipped the "ON" switch for the world's largest, most powerful radio telescope nestled in a vast, bowl-shaped valley in the mountainous southwestern province of Guizhou. The unrivaled precision of the...
The Five-hundred-meter Aperture Spherical Telescope (FAST) is nestled within a natural basin in China's remote and mountainous southwestern Guizhou province. Nicknamed Tianyan, or the Eye of Heaven, the new radio telescope is seen in this photograph taken near the start of its testing phase of operations on September 25.
