The [[Amaterasu particle]], named after the [[Amaterasu|sun goddess]] in Japanese mythology, was detected in 2021 and later identified in 2023, using the Telescope Array observatory in Utah, United States. It had an energy exceeding 240 exa-electron volts ({{val|2.4|e=20}} eV).<ref>{{Cite journal |last=Conover |first=Emily |date=January 13, 2024 |title=A high-energy cosmic ray hails from the void |url=https://www.sciencenews.org/article/rare-energetic-cosmic-ray-mysterious-origins |journal=[[Science News]] |pages=5}}</ref> This particle appears to have emerged from the [[Local Void]], an empty area of space bordering the [[Milky Way]] galaxy.<ref>{{cite journal |last1=Devlin |first1=Hannah |date=2023-11-24 |title='What the heck is going on?'
