JAKARTA (RIAUPOS.CO) – Astronomers are known to be confused by the emergence of the Amaterasu particle phenomenon, which is one of the highest energy cosmic rays ever detected originating from a seemingly empty region of space.
Reporting from The Guardian, astronomers were confused but have detected these rare and very high-energy particles. The particle, named Amaterasu after the sun goddess in Japanese mythology, is one of the highest-energy cosmic rays ever detected.

Only the most powerful cosmic events, on a scale far exceeding stellar explosions, are thought to be capable of producing such energetic particles. However, Amaterasu appears to emerge from the Local Void, an area of empty space bordering the Milky Way galaxy.
“You trace its trajectory back to the source and there’s no energy high enough to produce it,” said Prof John Matthews, of the University of Utah and co-author of a paper in the journal Science describing the discovery.
Amaterasu particles have energy exceeding 240 exa-electron volts (EeV), millions of times more than particles produced at the Large Hadron Collider, the most powerful accelerator ever built, and equivalent to the energy of a golf ball traveling at 95mph.
It is second only to the Oh-My-God particle, another ultra-high energy cosmic ray reaching 320 EeV, detected in 1991.
“Objects that are considered energetic, like supernovae, are not energetic enough for this,” Matthews said.
“You need a huge amount of energy, a very high magnetic field, to confine the particle as it accelerates,” Matthews said.
