Latest News
Change of the spokespersons of the Pierre Auger Collaboration is also noted in the in the march/april 2024 issue of the CERN Courier.
We are pleased to announce the release 2024, version 3, of our open data which extends the cosmic ray dataset to lower energies.
This is still an open question in astroparticle physics and a long-standing mystery that the Pierre Auger Observatory aims to solve.
Understanding the origin and nature of ultra-high energy cosmic rays has been one of the driving forces of the field of astroparticle physics. A key piece of information is what type of particles cosmic rays consist of.
