What term describes rapidly spinning neutron stars that sweep beams of radiation across space?

Answer

Pulsars

Neutron stars, resulting from the collapse of cores less than about three solar masses, possess several extraordinary characteristics stemming from their extreme density and formation process. They typically rotate at very high speeds, sometimes completing rotations many times per second, and they generate exceptionally powerful magnetic fields. When these magnetic poles are misaligned with the star's rotation axis, they emit focused beams of electromagnetic radiation, often observable as radio waves. As the star spins, these beams sweep across the cosmos; if one sweeps past Earth, we observe regular pulses of radiation, leading to the classification of these objects as pulsars. A single teaspoon of neutron star material, due to its density, would weigh billions of tons.
