Located in the mountains of Guizhou National Astronomical Observatories, it is being built 500 meters in diameter spherical radio telescope (FAST) Project integrated wiring project recently completed. (Taken from the People’s Daily)
National Astronomical Observatory of Chinese Academy of Sciences chief scientist Lee-di said radio unit, FAST is the largest building in diameter, the most powerful single-antenna radio telescopes, receiving area equal to about 30 football fields; built FAST will maintain world-class status in the next 20 years .
The main objective of FAST is to probe the universe distant signal and substance, in carrying out the origin of the universe to explore interstellar material structure of faint pulsars and other faint radio sources in the search for high efficiency to carry on the planet outside of rational life search and other tasks It is expected to make new contributions to the field of astronomy.
Reported that, FAST biggest feature is the cable net structure can be automatically changed with the movement of celestial bodies, led rope online activities 4450 reflecting panel synchronous adjustment; China Electric Division panel unit technical director 郑元鹏 said reflecting surface unit is a triangle, because the at different positions, the type of reflective surface elements there are nearly 400 kinds.
Zhengyuan Peng said that the installation will be based on the size of the cable network node coordinate data and unit requirements, design and production parameters of the method, the accuracy of the sub-surface control unit in a millimeter, so that each can focus reflective surface, FAST and known as “ground the largest machinery “Bonn, Germany 100 meters telescope sensitivity compared to an increase of about ten times.
Tim weapon and alien contact
WASHINGTON According to reports, it was said to be known as the “eye in the sky” FAST spherical radio telescope, is the latest secret weapon Chinese and alien contact. In this regard, China Electric Division Director Yang Dingjiang industry previously said that a goal of China’s spherical radio telescope is to detect aliens, but this is not the main scientific goals, its main goal is not to achieve the economic benefits in the short term, but to probe the universe distant signals and substances.
