| The world's largest radio telescope. FAST' which stands for 'Five-hundred-meter Aperture Spherical Telescope' |
The
world's largest radio telescope is in the final stages of completion,
measuring 500 metres in diameter, it is now 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.
Made up of over 4,500 mostly
triangular panels and its side panels measure 11 metres long, altering
the collective shape of the antenna
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.
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.

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.
It has taken more than five years to
build the world's biggest single-aperture radio telescope. It's on
schedule for completion in 2016
Some astronomers have said it will not
be long before new discoveries are found because of the advanced
technology and size of FAST
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.
