Join Victor Hess in his 1912 balloon journey to discover that cosmic rays produce muons in the atmosphere. Explore different types of cosmic ray detectors, such as scintillator and water detectors, and learn about arrays around the world. Discover the primary types of cosmic ray particles, including charged particles like protons and uncharged particles like photons. Uncover the potential source of the highest energy cosmic rays: active galactic nuclei. Dive into the Quarknet scintillation detector and find out how to determine the muon lifetime.
