China's Gigantic Telescope Detects Over 900 New Pulsars

GUIYANG, (APP - UrduPoint / Pakistan Point News - 17th Apr, 2024) China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, has identified more than 900 new pulsars since its launch in 2016, its operator said Wednesday.

Pulsars, or fast-spinning neutron stars, originate from the imploded cores of massive dying stars through supernova explosions.

Han Jinlin, a scientist with the National Astronomical Observatories under the Chinese academy of Sciences (NAOC), said that the pulsars included over 120 binary pulsars, more than 170 millisecond pulsars, and 80 faint and intermittent pulsars.

Han added that over the past 50-plus years since the discovery of the first pulsar, less than 3,000 pulsars were discovered worldwide, and the number of new pulsars discovered by FAST is more than three times the total number of pulsars found by foreign telescopes during the same period.

"The study has important implications for understanding the dense remnants of dead stars in the Milky Way and their radiation characteristics," Han said.
