  • AstroSat, has detected bright sub-second X-ray bursts from a new and unique neutron star with an ultrahigh magnetic field (magnetar).
  • This is expected to help understand the intriguing extreme astrophysical conditions of magnetars.
  • One of the key findings was the detection of 67 short sub-second X-ray bursts, with an average duration of 33 milliseconds.
  • Of these bursts, the brightest one lasted for about 90 milliseconds.
  • AstroSat is the India’s first multi-wavelength space-based observatory.
  • Magnetars are neutron stars having an ultrahigh magnetic field that are much stronger than the terrestrial magnetic field.
