The China-based FAST, the world's largest single-dish radio telescope, has identified two pulsars after one year of trial operation, the National Astronomical Observatories of China (NAOC) said on 10 October 2017. Two of the pulsars, named J1859-01 and J1931-01, are 16,000 light years and 4,100 light years from Earth with rotation periods of 1.83 seconds and 0.59 seconds, respectively. According to Li Di, Chief Scientist at the radio astronomy division of the NAOC, the two pulsars were discovered on 22 August and 25 August when FAST was drift-scanning the southern galactic plane. The discovery was confirmed in September by the Parkes radio telescope in Australia.
