China proposes largest solar telescope

BEIJING, Aug. 27 (UPI) -- Chinese scientists say they are looking for a site to built the world's largest solar telescope to gather data to help understand solar activities.

The proposed $90 million Chinese Giant Solar Telescope, "the next-generation [of] ground-based solar telescopes," will lead the field of solar observation in 20 years, Deng Yuanyong, director of the Huairou Solar Observing Station of the National Astronomical Observatories said.

The proposal is for a very large infrared and optical solar telescope, with spatial resolution equivalent to a 26-foot-diameter telescope and light-gathering power equivalent to a 16-foot-diameter full aperture telescope, Deng told China's state-run Xinhua news agency.

Currently the world's largest ground-based solar telescope is the 3-foot solar telescope of Sweden, with 5-foot solar telescopes soon to be launched by Germany and the United States.

"Although solar physics has made big progress with ground-based and space-borne observations in the past decades, it seems that we do need more efforts," Deng said.

The western part of the country, including Tibet Autonomous Region as well as Yunnan and Sichuan provinces, may provide candidates for the site of the proposed telescope with the right geological and weather conditions, scientists said.

"The site must stay far away from the hustle and bustle of cities, as well as modern industrialization," Lin Jun, chief scientist of the Chinese Academy of Science's Yunnan Observatory, said.

Base it in Tawang (South Tibet). The population there is less than 50 thousand and it is hardly industrialized. Perfect Chinese site.

^^^ Yeah right...
So that there us a burning monk outside the telescope every day.

Are you purposefully try to flame this thread...Mind you this thread is about a chinese Project which is real good...but Bring in an Indian District [ tawang ] and lets diagress and troll all the way to finsih line

This is in process of construction:

China building world’s biggest radio telescope

Since its completion in 1963, the Arecibo Observatory in Puerto Rico, with a diameter of 305 m (1,000 ft) and a collecting area of 73,000 square meters (790,000 sq ft), has been the largest single-aperture radio telescope ever constructed. But Arecibo is set to lose its title with construction now underway in Guizhou Province in southern China of the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Upon its expected completion in 2016, FAST will be able to see more than three times further into space and survey the skies ten times faster than Arecibo.

FAST was first proposed by China for the Square Kilometer Array (SKA), which has since opted to combine the signals of thousands of smaller antennae spread over a distance of more than 3,000 km (1,864 miles), combining for a total collecting area of approximately one square kilometer (0.38 square miles). The SKA will be built in the southern hemisphere with South Africa and Australia currently vying for the right to host the project.

Despite this, an international review and advisory conference on the science and technology of FAST held in Beijing in 2006 concluded FAST was feasible. In the following year funding for FAST was given the green light and the approved budget now sits at CNY700 million (approx. US$107.9 million). Construction in the Dawodang depression in south Guizhou commenced in March.

Unlike Arecibo, which has a fixed spherical curvature focusing radio waves into a line above the dish where they are focused to a single point by more mirrors, FAST's cable-net supporting structure will be able to deform the surface in real time through active control. As PopSci explains, this will allow a subset dish's 4,400 triangular aluminum panels to form a parabolic mirror anywhere within the larger bowl that is nearly the size of the entire Arecibo dish.

Using FAST's unparalleled sensitivity and high surveying speed, the project is expected to enable the surveying of neutral hydrogen in the Milky Way and other galaxies, the detection of new pulsars (both galactic and extragalactic), the search for the first shining stars, and of perhaps most interest to many people, the search for extraterrestrial life. It is expected to be able to detect transmissions from over 1,000 light years away.

With a construction period of 5.5 years, FAST is due to be completed in 2016.

WTF does India have to do with this?
This thread discussing a Chinese telescope that needs to be situated in a lightly populated and nonindustrial location. South Tibet is perfect. Please dont bring India into this.
