Pulsar
A pulsar is a highly magnetized, rotating Neutron star that emits electromagnetic radiation in a beam, which can be observed as pulses of radiation as the star rotates. Pulsars are formed when a massive star undergoes a Supernova explosion, leaving behind a dense core that rotates extremely rapidly. The rotation period of a pulsar can range from milliseconds to seconds, and its magnetic field is so strong that it can accelerate charged particles to high energies, producing intense beams of radiation. The discovery of pulsars has helped scientists understand more about Space (astronomy) and the behavior of matter in extreme conditions, such as those described by the Pauli exclusion principle. Pulsars have also been used to test theories of Gravity and have potential applications in Astronomy and Astrophysics.
