Photo taken on April 10, 2016 shows the single-aperture spherical telescope “FAST” in Pingtang county, southwest China’s Guizhou province. A total of 4,185 reflector panels, an equilateral triangle with a side length of 11 meters each, have been installed on the frame, indicating 94.04 percent of the installation work has been completed. The 500-meter aperture spherical telescope (FAST), to be completed within 2016, is expected to be the world’s largest, overtaking Puerto Rico’s Arecibo Observatory, which is 300 meters in diameter.
