The Pierre Auger Collaboration measured a dipolar anisotropy in the arrival-direction distribution of the cosmic rays with energies in excess of 8x10¹⁸ eV, finding that the flux is about
6.5% larger than the average in one direction of the sky and it is correspondingly smaller in the opposite direction.

Extensive air showers, initiated in the Earth’s atmosphere by high-energy cosmic rays, emit pulsed radio signals with a typical duration of tens of nanoseconds.

The Dutch organisation for Scientific Research (NWO) will fund a new antenna network at the Pierre Auger Observatory. The research group Cosmic Ray Research at Radboud University and Nikhef will receive 2.5 million € from the NWO Large Investment Grant programme.

The Pierre Auger Collaboration finds an indication that some galaxies may be better partners of cosmic rays at the highest energies than others.

The Pierre Auger Collaboration wins award of physicsworld.com: "To the Pierre Auger Observatory collaboration for showing that ultra-high-energy cosmic rays come from outside the Milky Way."
