A pulsar wind nebula (PWN) is a type of astronomical nebula formed by the wind of particles emitted from a rotating neutron star, known as a pulsar. Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles. As the pulsar rotates, these beams sweep across space, and when they are pointed towards Earth, they are detected as pulses of radiation, hence the name "pulsar.
