In 1967, a Cambridge student found a strange signal every 1.3 seconds, and changed astronomy forever

A graduate student's meticulous review of radio telescope data in 1967 led to a groundbreaking discovery. Jocelyn Bell Burnell identified a peculiar, repeating signal, initially dismissed as 'scruff.' This consistent 1.3-second pulse, unlike any known celestial phenomenon, proved to be the first evidence of neutron stars, revealing a new class of objects: pulsars.
