Meaning

(astronomy) A rotating neutron star that emits radio pulses periodically.

Example Sentences

Rapidly rotating dead stars, pulsars are so named because as they spin, they release beams of electromagnetic radiation across space that appear to pulse like celestial lighthouses. But a pulsar called PSR J1023+0038, located about 4,500 light-years away from Earth in the Sextans constellation, is even more unusual in that some of the pulses are brighter than others, almost like it’s switching between different modes.
