Construction Site of Biggest Radio Telescope on the World

The scoring to the Chinese Academy of Sciences Institute of national astronomical observatories of the largest radio telescope in the world is building in China. The start-up is scheduled for September 2016. The Chinese researchers promise greatly improved possibilities to be able to receive very weak signals, which may suggest the existence of life in the aliens space by the Super radio telescope.On the new, giant radio telescope, Guizhou is built in the Southwest Chinese province since March 2011. This area is almost deserted, so that there are hardly any local radio signals that might disturb the listening work of the telescope. The next human accommodation is five kilometres away, the next smaller place even 25 km.

The radio telescope is created in a natural inlet between roughly 500 m away, several hills on Karst surface that ensures a quick running of rain water. There is a visitors gallery on one of the hills.

A system of enormous size

The new facility is named after almost. These letters stand for “five hundred meter aperture spherical telescope”. Therefore the radio telescope with a diameter of 500 m. The biggest investment of the world – in Puerto Rico in the United States – bringing it to a diameter of 300 m. The bowl-like almost system consists of 4450 triangular panels, which each have a length of 11 meters.

The “bowl” rests on thousands of steel pillars. The individual panels of the bowl can be moved individually remote controlled by wires. Chief Engineer Zheng Yuanpeng specifies the precision of these movements with a millimeter. This allows it to align individual panels to certain signals from outer space.

Extreme precision in collecting the data

The head of the entire fast program, the scientists Nan Rendong, emphasizes the special ability of the new system to filter out certain signals from the variety of noises to be heard constantly from space. According to NaN, this is comparable to the task, in a strong storm from the noise of rain, storm and Thunder single cicadas who cause noise on the ground, to filter out.
