Browsing: Pulsars
Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles. As pulsars rotate, these beams sweep through space, and if aligned with Earth, can be detected as pulses of radiation, hence the name “pulsar.” These cosmic lighthouses are formed from the remnants of massive stars that have exploded in supernovae, leaving behind incredibly dense cores. Pulsars are known for their extraordinarily regular rotation rates, with periods ranging from milliseconds to seconds. The precision of their pulsing has been likened to atomic clocks, making them valuable tools for astronomers. They are used to study phenomena such as gravitational waves, the interstellar medium, and general relativity. The discovery of the first pulsar in 1967 by Jocelyn Bell Burnell and Antony Hewish marked a significant milestone in astrophysics, providing the first indirect evidence for the existence of neutron stars.
