China Central Television (CCTV) – A video of bird’s-eye view of world’s larges radio telescope, whose dish is the size of 30 football grounds, was released by CCTV (China Central Television) on Sunday.
The ambitious astronautics project, named Five-hundred-meter Aperture Spherical Telescope (“FAST”) owing to its 500-meter diameter, was under construction deep in the mountains of southwest China’s Guizhou Province.
Formed 45 million years ago with collapse of a karst cave, the hollow is now home to the radio telescope.
Built at a cost of 1.2 billion yuan (196 million U.S. dollars), the telescope is expected to be completed in September next year.
Technicians are assembling the telescope’s reflector, which is 500 meters in diameter and made up of 4,450 panels. Each panel is an equilateral triangle with a side length of 11 meters. Cables are fixed to the back of each panel so that it can change positions with an accuracy of 1 mm, ensuring the telescope can receive from different angles
Scientists say that it will become a big sensitive “ear”, listening to subtle sounds from distant universes, decoding cosmic messages.
