GRAPES-3 Muon Telescope Study

Recently, scientists at the GRAPES-3 Muon Telescope in Ooty analysed 22 years of data to study the relationship between Earth's upper atmosphere, solar activity, and cosmic rays.

  • The researchers analysed muon detections recorded by the GRAPES-3 Muon Telescope, one of the world's largest cosmic ray detectors.
  • Galactic cosmic rays are high-energy particles originating from deep space that continuously bombard the Earth's atmosphere.
  • When cosmic rays collide with oxygen and nitrogen atoms in the upper atmosphere, they generate secondary particles that decay into muons.
  • The findings demonstrate that ground-based muon telescopes can provide continuous, real-time monitoring of upper atmospheric temperature and ....
