Pierre Auger Observatory

The Pierre Auger Observatory, located in Argentina, is a large scientific facility dedicated to studying cosmic rays—high-energy particles from space. It uses a unique setup of ground-based detectors spread over a vast area, combined with telescopes, to capture and analyze the showers of particles created when these cosmic rays hit the Earth's atmosphere. By understanding these extreme events, scientists aim to uncover the mysteries of the universe, including the origins of these powerful particles and the processes that accelerate them in distant astrophysical sources.
