[หˆpสŒl.sษ‘หr ]

Definition

Context #1 | Noun

astronomy phenomenon

A pulsar is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. As the pulsar rotates, these beams sweep across the sky like a lighthouse beam, and if the Earth is in the path of the beams, they can be detected as regular pulses of radiation. These signals can be observed in radio, optical, X-ray, or gamma-ray wavelengths. Pulsars are known for their precise timing and can rotate anywhere from once every few milliseconds to several seconds.

Synonyms

magnetar, neutron star.

Examples of usage

  • The pulsar was discovered using radio telescopes.
  • Astronomers measure the regularity of pulsar signals.
  • Pulsars can help scientists test theories of gravity.
  • The first pulsar was discovered in 1967.

Interesting Facts

Astronomy

  • Pulsars are rapidly rotating neutron stars that emit beams of radiation, observed as pulses when aligned with Earth.
  • The first pulsar was discovered in 1967 by astronomer Jocelyn Bell Burnell, who initially thought it might be signals from aliens.
  • Some pulsars rotate hundreds of times per second, making them some of the most precise clocks in the universe.

Physics

  • The extreme density of pulsars is caused by the collapse of a massive star, where a teaspoon of neutron star material would weigh about as much as a mountain on Earth.
  • Pulsars emit energy across a wide spectrum, including radio waves, X-rays, and gamma rays, contributing to our understanding of cosmic phenomena.

Cultural Impact

  • The discovery of pulsars revolutionized astrophysics and led to the development of new theories regarding the life cycle of stars.
  • Pulsars have inspired various cultural references, appearing in literature, music, and films exploring space and science fiction themes.

Technology

  • Studies of pulsars have helped scientists test theories of general relativity by observing their precise timing and gravitational interactions.
  • Pulsars are being researched for potential use in navigation systems in space, as their signals can serve as cosmic waypoints.

Mathematics

  • The regular pulsing of these stars allows astronomers to utilize mathematical models to predict their behaviors and pulses over time.
  • The study of pulsars has led to the development of new algorithms in data analysis, improving how we interpret astronomical data.
