Discovery of Pulsars
1967 A.D.

A graduate student, Jocelyn Bell, and her professor, Anthony Hewish, discover intense pulsating sources of radio energy, known as pulsars. Pulsars were the first known examples of neutron stars, extremely dense objects that form in the wake of some supernovae. The crab pulsar, the tiny star in the middle of the Hubble Space Telescope image on the left, is the remnant of the bright supernova recorded by Native Americans and cultures around the world in the year 1054 A.D.
