Quick takeaways
- Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles, forming regular pulses of radiation as they rotate.
- Magnetars have the strongest magnetic fields in the universe, causing starquakes and powerful bursts of x-rays and gamma rays, and their study challenges our understanding of physics and compact stellar remnants.

Pulsars: Rapidly rotating neutron stars emitting focused beams of radiation
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles. These beams appear as regular pulses of radiation as the neutron star rotates. Pulsars are formed when the core of a massive star collapses during a supernova explosion, resulting in a concentrated magnetic field. The rapid rotation of the star, combined with the intense magnetic field, causes the emission of focused beams of electromagnetic radiation. These pulses are often observed in the form of radio waves.
