AdvertisementSpace scientists from the University of Utah and the University of Tokyo have identified an exceedingly rare, ultra-high-energy cosmic ray believed to have traveled from beyond the Milky Way galaxy.
Named the "Amaterasu particle" after the Japanese sun goddess, it is a subatomic entity, invisible to the naked eye.
However, high-energy cosmic rays, like the Amaterasu particle, are exceptional and are thought to come from other galaxies and extragalactic sources.
AdvertisementUnlike low-energy cosmic rays, whose origins are traceable, ultra-high-energy particles like this appear to come from seemingly empty spaces.
The Amaterasu particle is believed to originate from the Local Void, an empty region bordering the Milky Way galaxy.
