Astronomers involved with the Telescope Array experiment in Utah’s West Desert have detected an ultra-high-energy cosmic ray (UHECR) with a whopping energy level of 244 EeV, according to a new paper published in the journal Science. It’s the most energetic cosmic ray detected since 1991, when astronomers detected the so-called “Oh-My-God’ particle, with energies of an even more impressive 320 EeV. Astronomers have dubbed this
