The world’s largest radio telescope is in the final stages of completion,Going by the name of ‘FAST’ which stands for ‘Five-hundred-meter Aperture Spherical Telescope,’ the device is being constructed in Guizhou Province, south-west China,It has taken China more than five years to build the world’s biggest single-aperture radio telescope which covers the size of 30 football pitches and is currently running on schedule. Scientists carried out the last stages on Saturday, with hopes for a September 2016 completion.It will take a very long time to walk around the telescope which measures more than 500 metres in diameter and spans 30 football pitches.the reflector dish will collect up signals from the whole universe. The body of the telescope - which was first proposed in 2003 - is gigantic, measuring 500 metres across. The enormous dish is made up of over 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. This new antenna is capable of reflecting radio signals from the universe to a focal point, where the receiver dome sits.
