NASA spots 'cannonball' pulsar with speed of 40 lakh kmph

NASA has spotted a "cannonball" pulsar neutron star travelling at the speed of around 40 lakh kmph, fast enough to cover the distance between Earth and Moon in six minutes. Located about 6,500 light-years away, it spins 8.7 times a second, producing a gamma-ray pulse with each rotation, NASA said. The pulsar was discovered by a citizen-science project in 2017.
