Scientists have detected a powerful cosmic ray hitting the Earth. The oddity is that they don’t know “where it comes from or what exactly it is.”As explained by experts led by Toshihiro Fujii, professor at Osaka Metropolitan University Graduate School of Science and Nambu Yoichiro Institute of Theoretical and Experimental Physics.

Cosmic rays have high amounts of energy coming from galactic and extragalactic sources.
To give you an idea: In a publication for the special portal, scientists announced that they achieved an exaelectronvolt energy “about a million times more than the energy achieved by the most powerful accelerators ever produced by humans.” EurekAlert!.
Fujii has been studying these phenomena since 2008 with the Telescope Array, a major infrastructure in Utah, United States, equipped with hundreds of stations to detect them.
After years of experiments, On May 27, 2021, their devices showed that lightning struck with an energy of 244 exaelectronvolts (EeV).
The only record of something similar dates back to 1991, when other scientists detected the most powerful cosmic ray in history, which had an energy of 320 exaelectronvolts and which they called ‘Oh My God’ (Spanish for ‘Oh My God’). .

After verifications, Fujii concluded that his team had discovered the second most powerful cosmic ray. Details of the discovery are part of an article in the journal Science It was announced on November 24, 2023.
Unlike ‘Oh my God’, This second ray was christened Amaterasu, the name of the Japanese Sun goddess.
According to Fujii, lightning is as “mysterious” as the goddess herself, as she cannot determine its origin.

“No promising astronomical objects have been identified that match the direction from which the cosmic ray came, opening up possibilities for unknown astronomical phenomena and new physical origins beyond the standard model,” he said.
To know exactly where it comes from, They need to collect more data and even hope to test the next generation of observatories.
