Pulsars
Pulsars are highly magnetized, rotating neutron stars that emit beams of radiation from their magnetic poles. As they spin, these beams sweep across space like a lighthouse, producing regular pulses of radio waves, X-rays, or gamma rays detectable by telescopes on Earth. Formed from the remnants of massive stars that have exploded as supernovae, pulsars serve as cosmic laboratories for studying extreme physics, including gravity and matter in ultra-dense states. Their precise timing makes them valuable for navigation and testing theories in fundamental physics, including the nature of gravity and the behavior of particles under extreme conditions.

Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles. As they spin, these beams sweep across space like a lighthouse beam. If the beam points toward Earth, we detect regular pulses of radiation, hence the name "pulsar." These pulses can be extremely precise, with some pulsars serving as cosmic clocks. Pulsars provide valuable insights into the behavior of matter under extreme conditions, aiding our understanding of fundamental physics and the universe's evolution.
