Official ground-breaking ceremonies took place for a gigantic new 500 meter diameter radio telescope in China which will allow astronomers to detect galaxies and pulsars at unprecedented distances. The $102 million facility, known as the Five-hundred-meter Aperture Spherical Telescope (FAST), will have a collecting area more than twice as big as the 305 meter diameter [...]

Upon its finishing around September of 2016, FAST will be the most sensitive single-dish radio telescope in the low frequency radio bands between 70 MHz and 3 GHz.

Completion still September 2016. Some very nice pictures of their progress to date.

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.

Construction of the 124 million (1.2 billion Yuan) project began in March 2011 and is expected to complete in September 2016.

Technicians are currently assembling the telescope's reflector, which is made up of 4,450 triangle-shaped panels.

To ensure that the completed telescope can receive signals from different angles, engineers have fixed cables to the back of each panel so that it can change positions with an accuracy of 0.03 inches.

It will allow scientists to get weaker radio signals from outer space, even further than our solar system, according to an earlier report on People's Daily

Jerry Dome part II.

Now for a radio telescope like this on the moon.
