Illustration of the Pierre Auger Observatory. The observatory uses 1600 particle detectors spaced uniformly over 3000 square kilometers to record cosmic ray air showers. On dark nights, sensitive light sensors observe the faint fluorescence caused by collisions of air shower particles with air molecules in the atmosphere. A photo of the Auger Collaboration.
