China begins testing world’s largest radio telescope as construction of the £124 MILLION project enters final stage
- Measuring 500 metres in diameter, the huge machine is being built in Guizhou Province, south-west China
- The device goes by the name of ‘FAST,’ which means ‘Five-hundred-metre Aperture Spherical Telescope’
- Project is running on schedule with hope of a September 2016 completion, testing was carried out on Saturday
Measuring 500 metres in diameter, the world’s largest radio telescope is in the final stages of completion, and is being put through its paces with a dry run.
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, reports The People’s Daily Online.
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 up to 40 minutes to walk around the telescope which measures more than 500 metres in diameter and spans 30 football pitches
Made up of over 4,500 mostly triangular panels and its side panels measure 11 metres long, altering the collective shape of the antennaa
Scientists spent the weekend testing the largest telescope in the world which goes by the name of FAST, situated in southeast China
Chinese authorities and engineers tested a key component inside the massive telescope before it goes live indefinitely.
Over the weekend, the retina was successfully installed and tested in the telescope.
A mechanism that weighs 30,000 kilograms and is suspended 160 metres above the reflector dish, which is still unfinished.
According to The China Daily, 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 (half a mile).
It will take up to 40 minutes to walk around device.
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.
The new antenna is capable of reflecting radio signals from the universe to a focal point, where the receiver dome sits.

China is building the world’s biggest radio telescope that’s the equivalent of 30 football pitches so it can ‘listen to the universe from earth’
The gigantic telescope will cost approximately 1.2 billion Yuan (£124 million), making it the biggest astronomy project China has ever had
Speaking to reporters, Li Di, a chief scientist from the Chinese Academy of Sciences said: ‘So far, one of the most important steps has been completed.
‘We will finish installing all the panels by June 2016, and strive to debug the whole system by the end of September.’
He added that the design of the telescope is not difficult to understand, very similar to a TV antenna: ‘FAST is similar to any television antenna on a roof, but it is so much larger that.
‘With a larger signal receiving area and more flexibility, FAST will be able to scan two times more sky area than Arecibo, with three to five times higher sensitivity,’ said Li.
Some astronomers have said it will not be long before new discoveries are found because of the advanced technology of FAST.
But not just new ones, Lister Staveley-Smith, an astronomer at the University of Western Australia, expects it to find unknown stars in the Milky Way other more distant galaxies.
‘FAST’s sensitivity and resolution will allow an extremely comprehensive study of thousands of galaxies in different environments in the local universe,’ he said.
After the completion of its detection, FAST is expected to maintain world-class status for the next 20-30 years.
The gigantic radio telescope will cost approximately 1.2 billion Yuan (£124 million), making it the biggest astronomy project China has ever had.
Measuring 500 metres in diameter, the huge radio telescope is being built in Guizhou Province, southwest China
FAST is located in the Dawodang depression, a huge karst valley in Pingtang County, Guizhou Province. It took the scientists as long as 17 years to find a hollow in the country large enough to accommodate the dish, which has a diameter of 1,640 feet.
The natural landscape of Dawodang depression provides the perfect size and shape for the construction of the telescope. The ground also provides enough support for the gigantic telescope.
The porous soil forms an underground drainage system that protects the telescope.
With only one town in the 12 miles radius, the Dawodang depression is extremely isolated from magnetic disruptions.
The remoteness of the location also protects the surrounding landscape from any damage.
