These include an eclipsing binary millisecond pulsar in globular cluster Messier 92. For example, FAST detected more than 240 pulsars and pulsar candidates by November 2020. Researchers will be able to conduct studies and observations across a range of areas of interest, including pulsar discovery, galaxy evolution, and the large-scale nature of the universe. FAST PossibilitiesįAST features an innovative 19-beam receiver developed by Chinese and Australian scientists that enables sensitive observations for a number of scientific goals. The telescope began operations in September 2016 and officially entered service on January 11, 2020. "We drew a lot of inspiration from its structure, which we gradually improved to build our telescope,” Wang said. Wang Qiming, chief inspector of FAST's operations and development center, told AFP in December, that he had visited Arecibo, which influenced China’s own plans. FAST also has a greater effective collecting area (71,000 square meters), than the 305-meter-wide Arecibo (50,000 square meters). However, unlike Arecibo, its receivers do not have radar capability, so it cannot investigate near-Earth objects.įAST is more than 2.5 times more sensitive than Arecibo, according to the National Astronomical Observatories, under the Chinese Academy of Sciences, which means that FAST can see fainter sources from farther away. With a deeper dish and panel system, FAST can cover a swath of sky within 40° of its zenith, while Arecibo was limited to 20°. This allows researchers to maneuver to focus on different areas of the sky. The dish itself consists of 4,450 triangular panels, which can be controlled by more than 2,000 mechanical winches. Like Arecibo, FAST’s receivers are suspended high above the dish. National Astronomical Observatories of China FAST and Arecibo This picture shows the karst depression where FAST was built. Nearby settlements were relocated to reduce electromagnetic emissions which could interfere with the telescope’s sensitive operations.
FAST’s collecting area and sensitivity are expected to make a range of contributions to radio astronomy and are therefore of great interest internationally.Īlso known as Tianyan, or the Eye of Heaven, FAST is the world’s largest single-dish telescope, situated in a karst depression in Pingtang, Guizhou province in southwest China.
The facility’s scientific committee also stated that FAST will become increasingly open to international teams. Jiang Peng, FAST's chief engineer, said about 10% of the observation time will be allocated to foreign scientists in the first year of the telescope's opening to the global scientific community. National Astronomical Observatories of China The telescope came fully online in January 2020.

This diagram represents a pulsar detected during FAST's trial period. A timetable for observation will then be published by August 1st. The National Astronomical Observatories of China (NAOC), the telescope’s operator, confirmed on January 4th that scientists outside of China will be able to apply for time using the facility on April 1st. China is making its Five-hundred-meter Aperture Spherical Telescope (FAST) available to international scientists in the wake of the collapse of the Arecibo telescope in Puerto Rico late last year.
