An object that astronomers thought was a distant galaxy has now been discovered as the brightest extra-galactic pulsar ever seen.
  • This pulsar could be the most luminous one ever found- 10 times brighter than any other detected.
  • The newly found pulsar – called PSR J0523−7125 – is located well beyond the limits of the Milky Way within the Large Magellanic Cloud.
  • A pulsar (from pulsating radio source) is a neutron star that rotates quickly and releases two polarised radio lights.
  • The beams create a unique timing and polarisation signature as they burst across space.
  • Pulsars are among the few celestial objects that emit circular polarised light.
Three distinct classes of pulsars are currently known to astronomers, according to the source of the power of the electromagnetic radiation:
  1. rotation-powered pulsars, where the loss of rotational energy of the star provides the power,
  2. accretion-powered pulsars, where the gravitational potential energy of accreted matter is the power source (producing X-rays that are observable from the Earth),
  3. magnetars, where the decay of an extremely strong magnetic field provides the electromagnetic power.
Hence both statements are correct.
