The construction of the highly sensitive telescope began in March 2011 and is due to be completed next year. On Thursday, technicians already began attaching 4,450 triangular-shaped panels to the telescope's reflector. To overlook the whole reflector, visitors will reportedly have to climb up to the top of one of the hills. An observation platform is currently said to be under construction.

The chief scientist of the FAST project, a Chinese astronomer Nan Rendong, explained that the bigger the dish is, the more powerful the telescope.

"A radio telescope is like a sensitive ear, listening to dustinguish meaningful radio messages from white noise in the universe. It is like identifying the sound of cicadas in a thunderstorm," the scientist said.

The so-called Karst topography in the surrounding landscape is ideal for draining rainwater underground and protecting the reflector, according to Chinese scientists, adding that the surrounding area is characterized by a certain "radio silence."

The dish will shift to receive radio signals from different angles.

"Panels can change their positions through connected wires and parallel robots. We can control their position with an accuracy of 1 mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua.

It's hoped that the new telescope will boost Chinese scientists' capacity to observe outer space.

Wu Xiangping, director-general of the Chinese Astronomical Society, lamented that for years local scientists had to work on "second hand" data collected by other researchers.

"Having a more sensitive telescope, we can receive weaker and more distant radio messages. It will help us to search for intelligent life outside the galaxy and explore the origins of the universe," Wu said.

Earlier this week, it was reported that Russian internet billionaire Yuri Milner will be funding a project, backed by Stephen Hawking, to scan the skies in the search for alien life. Two of the world’s largest telescopes (in West Virginia and in New South Wales) will be used during the epic hunt.

“I think it’s an important project for the whole humanity. We now have the technology, we have the capability, we have the software and hardware to really try to get to the answer to this pretty fundamental question: are we alone in the universe? And I think in the next 10 years we will be able to make significant progress, which in order of magnitude more significant than in the last 55 years,” Milner, whose background is physics, told RT on Thursday.

I guess different. The above is more of an international project with telescopes spanning several countries


China contributes to world's largest radio telescope
- Xinhua | English.news.cn

BEIJING, Oct. 3 (Xinhuanet) --China has joined the international effort to build the Square Kilometer Array, the largest radio telescope in the world.

This new global scientific undertaking will help uncover the mysteries of the universe.

The Square Kilometer Array project is the largest and most sensitive radio telescope in the world.

As its name suggests, the telescope will deploy huge fields of antennas across Africa and Australia, with a combined collecting area of about one square kilometre… or the size of about 140 soccer pitches.

The aim is to help astronomers study the sky in monitor with an unprecedented level of detail.

With its headquarters based at the world famous Jodrell Bank site near Manchester, the SKA project will build thousands of antennas across two continents, and completely change our understanding of the universe.

"The Square Kilometre Array, the SKA, is the next generation of the radio telescope, a much big version of the telescope you see behind me, much more capable. It will be fundamentally the instrument does science, exploring the true nature of gravity, looking at the universe is like around us. We want to try to understand the formation of planet, and even to detect signal from extraterrestrial civilization if they exist," Professor Philip Diamond, director general of SKA, said.

The SKA is one of the largest scientific endeavors of the 21st Century, and its sheer scale means it has to be an international collaboration.

The project brings together top scientists, engineers and policy makers from 20 countries, who are now in the process of establishing an inter-governmental organization to help formalize the relationship between the project and its members.

"We have agreed the best way of doing it is to set up an international organization. So this will be an organization where varies governments come together and sign a treaty, and create an organization which is fit for purpose for lasting for fifty to sixty years while the observatory is running. We have a number of countries, most recently including China, all made commitment to say they gonna work together to establish this organization. And the first meeting to establish this process is gonna take place in a few weeks led by Italian government in Rome," Simon Berry, director of Policy Dev't, SKA, said.

From the early stages China played an important role in the project, contributing several key technology developments.

The government will also join the negotiations with other member nations to define the level of contribution.

"The Chinese contribution will be cash contribution, together with in-kind contribution. China will deliver its products and technology needed for the project, such as antennas. China has very strong potential in this particular field. And like with time synthesizers, Tsinghua University got involved and also shows their strength. They all demonstrate China’s technology capabilities and contributions to the project," Dr. Qiming Wang, Head of Policy Dev't, SKA, said.

With preparation well underway, construction of the SKA project is set to start in 2018 with the telescope set to receive its first batch of data two years later.

LONDON, May 1 (Xinhua) -- The world's largest radio telescope is to be headquartered in a rural area of northern England, it was announced Friday.

Jodrell Bank Observatory in Cheshire is already home to an existing radio telescope, attracting tens of thousands of visitors every year as a tourist attraction.

Now the famous observatory will remain at the forefront of global scientific research for at least another 50 years after members of the international Square Kilometer Array (SKA) project chose Jodrell Bank as their headquarters.

Scientists say the SKA telescope will have the capability to look all the way back to the aftermath of the Big Bang. The facility will spread across several continents and comprise of 2,500 dishes and 1 million antennae.

The project will generate around 1.5 billion U.S.dollars of private sector investment and will create up to 200 new jobs at the Jodrell Bank base.

Professor Philip Diamond, director general of the SKA Organisation said: "I am delighted a permanent home for the SKA headquarters has been identified. Clarity over the location of the headquarters is an important step for SKA."

Professor Stephen Watts, who heads the School of Physics and Astronomy at the University of Manchester said: "This is great news for Jodrell Bank. Not only will it mean cutting-edge science will continue to be carried out at the site for the foreseeable future, but it will also help inspire the thousands of children who visit Jodrell Bank every year from schools across the country."

The plan is supported by Britain's Science and Technology Facilities Council, the Universities of Manchester, Oxford and Cambridge Universities and the local authority covering the area, Cheshire East Council.

The project envisages designing and constructing a unique campus for one of the most inspirational science projects of the 21st Century, said a spokesman for the SKA Partnership, adding the Cheshire site offers the grow if the project requires it in the future.

The SKA project is an international effort to build the world's largest radio telescope to conduct transformational science to improve understanding of the universe and the laws of fundamental physics. It will monitor the sky in unprecedented detail and mapping it hundreds of times faster than any current facility.

The SKA project is backed by 11 member countries, Australia, Canada, China, Germany, India, Italy, New Zealand, South Africa, Sweden, The Netherlands and the United Kingdom. It has brought together some of world's finest scientists, engineers and policy makers and more than 100 companies and research institutions across 20 countries in the design and development of the telescope.

Construction of the SKA is due to start in 2018, with early science observations in 2020

Yes Thanks.
I know that is in Guizhou and we are in process of building the world's largest radio telescope but as @TaiShang and @bobsm pointed out, we are also joining an international group building "another" world's largest radio telescope so I am a bit uncertain if the one we are building are going to be ecliped by the one to be built by international efforts.

@Martian2 , sir, your input?

@Martian2 , sir, your input?

The thing that China is building is a radar single aperture telescope. Single aperture is to be highlighted.

The largest general radio observatory would be International collaboration.

 

[Martian2]

@Martian2 , sir, your input?

China's FAST radio telescope has a 500 meter diameter (or 250 meter radius).

The current record holder Arecibo has a 305 meter diameter (or 153 meter radius).

Area = π*r^2

China's FAST = π * (250 meter) ^ 2 = 196,250 meter squared detector

Arecibo = π * (153 meter) ^ 2 = 73,504 meter squared detector

Sensitivity of China's FAST radio telescope = 196,250 / 73,504 = 2.67 times more sensitive than Arecibo

He's asking a very different question.

There is obviously FAST that is being built by China.

And there is the Square Kilometer Array being built by International Colloboration, both of which were listed as the largest telescopes. So which is true?

Also, Arecibo is a really old telescope.

China Launched Its First Typhoon Detecting Missile

China's first typhoon detecting rocket was launched 11p.m. in Hainan Wanning on Oct. 3. Several radiosondes were dropped into the center of Typhoon Mujigae only 6 minutes after the launch. The data retrieved from this launch was very accurate, with high scientific research value. This experiment is a breakthrough in China’s rocket science, with rocket launching, radiosonde dropping and remote data retrieval achieved at the same time.

The launch is collaboration between Shanghai Typhoon Institute of China Meteorological Administration and China Aerospace Science & Industry Corp. It took three years and the support from Hainan Meteorological Service to complete this launch. Scientists said there’s great potential in applying rocket science into typhoon detection and forecast.
