Answer 1

A pulsar emits **electromagnetic radiation**. Pulsars are highly magnetized rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles. As they rotate, these beams sweep across space, and if they point towards Earth, they can be detected as pulses of radiation, which is how they get their name.
