Jocelyn Bell and her advisor, Anthony Hewish, were studying radio signals from space with the aim of detecting signals from extraterrestrial intelligence (SETI). However, they discovered a series of pulsating radio signals which they initially named "LGM-1" (Little Green Men 1) before realizing that they had discovered a new type of astronomical object: pulsars. This discovery earned Hewish and Bell the 1974 Nobel Prize in Physics. Jocelyn Bell, then a graduate student at Cambridge University, was working with her supervisor, Anthony Hewish, on a project using a radio telescope to study quasars. While analyzing data, Bell noticed a series of unusual radio signals that appeared to be coming from a single point in the sky. After ruling out the possibility of human-made interference, Bell and Hewish hypothesized that the signals could be coming from a new type of astronomical object. They nicknamed the object "LGM-1" (short for "little green men") before later determining that it was a rapidly rotating neutron star, now known as a pulsar. Bell's discovery was one of the most significant astronomical achievements of the 20th century and she later became the first female president of the Royal Society of Edinburgh.
