The Sky at Night (1957)

Season 20: Episode 6

Pulsars are among the most incredible objects known to man. They are composed of neutrons and are so dense that a pin's head of neutron star material would weigh as much as an ocean liner. Discovered as recently as the late 60s, neutron stars are of great and increasing interest to astronomers and valuable information on X-ray pulsars has been obtained from the instruments aboard the British satellite, Ariel 5. Patrick Moore talks about pulsars to Jocelyn Bell Burnell who was involved in their discovery.
