China begins testing world’s largest radio telescope as construction of the £124 MILLION project enters final stage of completion, measuring 500 metres in diameter, being put through its paces with a dry run. The project name is called ‘FAST’ which stands for “Five-hundred-meter Aperture Spherical Telescope” the device is being constructed in Guizhou Province, south-west China. The project has taken more than five years to build world’s biggest single-aperture radio telescope which covers above the size of 30 football pitches and is presently running on schedule. Scientists carried out the last stages with hopes for a September 2016 completion.
Moreover, Chinese authorities and engineers tested important component inside the gigantic telescope before it goes live indefinitely. Thusa, a mechanism that weighs more than 30,000 kilograms and is suspended 160 metres above the reflector dish, which is still unfinished, and the reflector dish will collect up signals from the whole universe. The project was first proposed in 2003, as body of telescope measuring 500 meters across. Therefore, the huge dish is made up of more than 4,500 mostly triangular panels and its side panels measure 11 metres long, the motion of these panels alter the collective shape of the antenna. The new antenna is adept of reflecting radio signals from the universe to a focal point, where the receiver dome sits.
The design of the telescope is not too much difficult to understand, it is very similar to a TV antenna: “FAST” is similar to any television antenna on a roof, but it is so much larger that. Some astronomers predict it will not be long before new discoveries are found because of the advanced technology of FAST and also expect it to find unidentified stars in the Milky Way other more distant thousands of galaxies in different environments in the local universe. After the completion of its detection, FAST is expected to maintain world-class status for the next 20-30 years. Moreover, the massive radio telescope will cost about 1.2 billion Yuan (£124 million), making it the biggest astronomy project China has ever had. The remoteness of the location also protects the surrounding landscape from any damage. Source: Dailymail
