During November 14 - 17, 2015, the Pierre Auger Collaboration celebrated the inauguration of AugerPrime. Spread over an area of 3000 km2 in the 'yellow pampa' in western Argentina, Auger is the largest cosmic ray experiment in the world. AugerPrime allows the Czech researchers to contribute to discerning the mysteries of ultrahigh energy cosmic rays until 2025.
The Pierre Auger Observatory is the world’s leading science project for the exploration of cosmic rays. The Observatory has achieved excellent results helping scientists to better understand particles with energies more than million times larger than the beam energy at the current world largest accelerator.
