Rapidly rotating neutron starsPulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles12345. They have strong magnetic fields that funnel particles along their magnetic poles, accelerating them to relativistic speeds, which produces two powerful beams of light, one from each pole1. Pulsars are the ultra-dense leftover core of a massive star3. They emit beams of radiation that sweep out in circles as the pulsar spins, and when those beams flash over Earth, we see them as regular, repeating pulses of radio emission3.Learn more:âś•This summary was generated using AI based on multiple online sources.
