Gigantic telescope

CHINA’S Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world’s largest single-dish radio telescope, has identified over 800 new pulsars since its launch in 2016, its operator said Tuesday.

The number of new pulsars discovered by FAST is more than three times the total number of pulsars discovered by foreign telescopes during the same period, said Jiang Peng, chief engineer of the telescope.

Pulsar observation is an important task for FAST, which can be used to confirm the existence of gravitational radiation and black holes, and help find answers to many other major questions in physics.
