Pierre Auger

The Pierre Auger Observatory is a scientific facility located in Argentina that studies cosmic rays—high-energy particles from outer space. It consists of thousands of detectors spread over a large area to capture these particles when they collide with the Earth's atmosphere. By analyzing the data collected, researchers aim to understand the origins, compositions, and behaviors of these energetic cosmic events, which can have implications for astrophysics and the fundamental understanding of the universe. Named after physicist Pierre Auger, the observatory helps advance our knowledge of some of the most powerful phenomena in nature.
