- Scientists have detected an extremely rare ultra-high-energy particle believed to have come from beyond the Milky Way.
- The particle has been nicknamed as 'Amaterasu' particle after the sun goddess in Japanese mythology.
- The Amaterasu particle has an energy exceeding 240 exa-electron volts (EeV).
- This is equal to millions of times more than particles produced in the Large Hadron Collider.
- It comes only second to the Oh-My-God particle, another ultra-high-energy cosmic ray that came in at 320 EeV, detected in 1991.
- Cosmic rays pose potential hazards to astronauts in space and high-altitude flights, as they can penetrate spacecraft and aircraft.
- Prolonged exposure to cosmic rays can lead to increased risks of cancer and other health issues.
