Cosmic Rays Shed Light on Stone Age TimelinesCaroline HaslerEos, TRANSACTIONS, AMERICAN GEOPHYSICAL UNION
visible light has an energy around 1 eV, X-rays are approximately103eV, and emissions from radioactive decay, such as alpha, beta, and gamma rays, are in the range of106eV. Particles such as electrons and protons in the solar corona, where the temperature is around 1 million degrees, ha...
This composite photo taken on April 21, 2023 shows the Large High Altitude Air Shower Observatory (LHAASO) at an altitude of 4,410 meters on Mount Haizi in Daocheng County, southwest China's Sichuan Province. China's cosmic ray observatory has discovered a giant ultra-high-energy gamma-ray b...
High-resolution radio measurements of air showers—cascades of secondary particles in the atmosphere initiated by cosmic rays—reveal that cosmic rays with energies of 1017–1017.5 electronvolts have a mixed composition, with light elements (protons and

Cosmic rays interacting in the Earth’s atmosphere produce atmospheric neutrinos, which form an experimental background to cosmic neutrinos. To detect cosmic neutrinos, very-large-volume neutrino observatories monitor natural bodies of water or ice for the Cherenkov light induced by the passage of the...
