Jeff Dai just attended the opening ceremony of the largest radio telescope in the world.
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.
