Resumen:
The Earth is exposed to a permanent rain of cosmic particles fromouter space [1]. Most of the particles are fully ionised atomic nuclei,moving with relativistic energies. The bulk of them with energies upto 1017 eV originate within our Milky Way. They are most likely acceleratedin supernova remnants. Some particles have a thousand timeshigher energies, i.e., around 1020 eV. This corresponds to the kineticenergy of a tennis ball with a mass of 50 g and a velocity of 90 km/h.
