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.
