High-Energy Particle “Amaterasu”

Japanese scientists have discovered an ultra-high-energy cosmic ray in May 2021, which was named ‘Amaterasu’ after the Japanese sun goddess.

• One of the most powerful cosmic rays ever recorded, Amaterasu baffled scientists due to its unprecedented energy level exceeding 240 exa-electron volts, millions of times more potent than particles produced by the Large Hadron Collider.
• Detected during a routine data check at the Telescope Array Project in Utah on May 27, 2021, the ultra-high-energy particle arrived from a void in space where few galaxies exist, challenging scientists to explain its enigmatic origin.
• Proposed explanations include an unidentified source, unexpected magnetic deflection, or the ....
