Extensive Air Showers (EAS)

Extensive Air Showers (EAS) occur when high-energy cosmic rays from space enter Earth's atmosphere and collide with atmospheric particles. These collisions create a cascade of secondary particles, including pions, muons, electrons, and gamma rays, which spread out and travel toward the ground. This cascade forms a large, detectable shower of particles over a wide area. Scientists study EAS to understand the origins and properties of cosmic rays, helping investigate phenomena beyond our planet, such as supernovae or black holes. The detection of these showers provides vital clues about high-energy processes in the universe.
