The detected cosmic ray had an estimated energy of 244 EeV, comparable to the most energetic cosmic ray ever observed (Osaka Metropolitan University/L-INSIGHT) (CN) — Researchers out of Osaka, Japan, ...

Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 exa-electronvolts. Its apparent arrival from a nearly empty region of space ...

Astronomers have detected a rare and extremely high-energy particle falling to Earth from space. Named Amaterasu, after the sun goddess in Japanese mythology, it is one of the highest-energy cosmic ...

Particle physics is using ever more interdisciplinary means to seek ever more exotic phenomena, Robert P Crease finds, but ...

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far ...

Researchers have detected one of the highest-energy particles ever falling to Earth. Cosmic rays are high-energy particles that come from sources in space such as the sun, but this recent detection is ...

A deep-sea neutrino telescope has detected the most energetic neutrino ever recorded. The particle, known as a "ghost particle," was about 30 times more active than the previous record-holder.
