New Delhi, (PTI) Researchers have detected the second-most powerful cosmic ray to have come from outside our galaxy. But the exact origin of this “ultra-high-energy” particle from outer space remains a mystery.
Observed in Utah, this is believed to be the most powerful cosmic ray detection since the ‘Oh-My-God’ particle in 1991 that left physicists puzzled.
Named ‘Amaterasu’ particle after the sun goddess in Japanese mythology, the second-most powerful cosmic ray has energy equivalent to “dropping a brick on one’s toe from waist’s height”, the international team of physicists mentioned in their study published in the journal Science.
