China's FAST Radio Telescope Discovers over 1,000 Pulsars in 2024

China's FAST Radio Telescope Discovers over 1,000 Pulsars in 2024

China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the world's largest radio telescope, keeps scanning the stars from the remote mountains of Guizhou as the country celebrates Spring Festival. Nicknamed "Sky Eye", FAST runs 24/7, helping scientists uncover the mysteries of space, from faint neutron stars (pulsars) and cosmic radio bursts to low frequency gravitational waves. At least 10 per cent of the available observation time is reserved for international astronomers.

Maintaining a 500-meter telescope, the size of 30 football fields, is a big job.

By November 2024, China’s FAST telescope has found over 1,000 pulsars, more than all other telescopes combined. These spinning stars flash like cosmic lighthouses, sending steady signals that could one day help guide our spaceships through the universe.

The telescope is located in a naturally deep and round karst depression in China's southwestern province of Guizhou.

The primary driving force behind the FAST project was Nan Rendong, a researcher with the Chinese National Astronomical Observatory, part of the Chinese Academy of Sciences. He held the positions of chief scientist and chief engineer of the project. He died September 15, 2017, in Boston, United States due to lung cancer.
