Pulsar. Illustration of a pulsar (upper left) over the rocky landscape of an imaginary planet. Pulsars are thought to be neutron stars that spin around rapidly,producing pulses of radiation in the same way that a lighthouse produces flashes of light. A neutron star is the tiny but extremely dense star that remains after a dying star explodes to produce a supernova. The first pulsar was discovered in 1967 and hundreds are now known. Many produce pulses of radio waves but some flash in visible light,X-rays or gamma rays | |
