High energy particle telescopes

research project to observe air showers

very large surface array designed to study the origin of ultra-high-energy cosmic rays

experiment in astroparticle physics, sited at CERN in Switzerland

The Extreme Universe Space Observatory onboard Japanese Experiment Module (JEM-EUSO) is the first space mission concept devoted to the investigation of cosmic rays and neutrinos of extreme energy (). Using the Earth's atmosphere as a giant detector, the detection is performed by looking at the streak of fluorescence produced when such a particle interacts with the Earth's atmosphere.
