China Building World's Largest Radio Telescope--"Will Search for Intelligent Life Outside of Milky Way"

"Having a more sensitive telescope, we can receive weaker and more distant radio messages," Wu Xiangping, director-general of the Chinese Astronomical Society, was reported as saying. "It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe."

China has started assembling the world's largest radio telescope, which will have a dish the size of 30 football pitches when completed, state media reported as Beijing steps up its ambitions in outer space.

The five-hundred-metre Aperture Spherical Radio Telescope (FAST) nestles in a bowl-shaped valley between hills in the southwestern province of Guizhou, images posted online show.

Technicians began attaching 4,450 triangular-shaped panels to the telescope's reflector on Thursday, the official Xinhua news agency reported.

FAST will be the world's largest single-aperture telescope, it said, overtaking the Arecibo Observatory in the US territory of Puerto Rico, which is 305 metres (1000 feet) in diameter.

For years Chinese scientists have relied on "second hand" data collected by others in their research and the new telescope is expected to "greatly enhance" the country's capacity to observe outer space, Xinhua said.

Beijing is accelerating its military-run multi-billion-dollar space exploration programme, which it sees as a symbol of the country's progress. It has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

The dish will have a perimeter of about 1.6 kilometres, Xinhua said, and there are no towns within five kilometres, giving it ideal surroundings to listen for signals from space.

The region's karst topography -- a landscape of porous rock fissured with deep crevasses and underground caves and streams -- is ideal for draining rainwater and protecting the reflector, it added.

Construction on the telescope started in March 2011 and is scheduled to finish next year, Xinhua said.

A military complex, eh? Interesting, eh?
However it gets constructed it will be a great boon to astronomy. Eh?

Outside this galaxy? What a waste of money (if that is the real purpose)

Wow, and I can't even get AT&T to provide me with decent cell coverage from my living room to make an order from Domino's pizza.

Bigger than Arecibo Observatory? A military complex? They will breed some BIG chupacabras there...

Indeed science in the technological and experimental field has made great progress. But in theoretical field, science is in a wrong direction: so its progress in this field is perhaps negative.
All these create to me the query. Does science builds a giant with toddler's mind?

Wow, the chinese can`t even feed their populace and they still curb democracy how can the waste money on foolish projecs like that ?

They don't, Knize 10, they don't. The question is: what's the real plan???

Well, Ted H it occurs to me that the variable motion of the independent reflectors also means it has the ability to change the focal point. Say instead of from several hundred meters where the receiving detector is suppose to be, to a very precise point above the atmosphere like the orbits of various satellites or pesky USA spy drones. A ground based Golden Eye, if you will. Harnessing that much incoming solar power would make for one helavabig energy weapon.

Finding alien life will prove to be as difficult as finding a single piece of fly crap in a 55 gallon drum of pepper.

Hello. Have they given up looking inside the galaxy?
