Atmospheric fluorescence is the basis for the Pierre Auger Observatory's method of finding them.
The exposure of CCDs on the ground is limited by these particles, which creates a namesake background that can lead to the detection of false stars. The Haverah Project is an ongoing project that detects them. Atmospheric fluorescence is the basis for the Pierre Auger Observatory's method of finding them. PAMELA, CHICOS, and CASA are projects researching the effects of these particles, which interact with other nucleons during a namesake spallation process that is one source of baryonic matter. They produce pions and kaons when they collide with particles in Earth's atmosphere and are composed of 90% hydrogen nuclei and 9% alpha particles. For 10 points, what are these high energy particles that bombard Earth's surface?
