The International Collaboration: 

The International Collaboration “Earth. The Blue Planet. The known space is enclosed in the lower left corner. The unknown space opens in the upper right corner. Two Auger Observatories installed in both hemispheres. Two eyes looking for information from the unknown space.” Countries involved: Argentina, Armenia, Australia, Bolivia, Brazil, China, France, Germany, Greece, Italy, Japan, Mexico, Poland, Slovenia, Russia, United Kingdom, USA, Vietnam (18 countries).
