The Earth's atmosphere has been blasted by the second strongest ultrahigh-energy cosmic ray (UHECR) to ever be observed. While its exact origins remain unknown, astrophysicists are pointing the finger ...

Scientists have detected the most powerful cosmic ray seen in more than three decades. But the exact origin of this turbocharged particle from outer space remains a mystery, with some suggesting that ...

Ever since French physicist Pierre Auger proposed in 1939 that cosmic rays must carry incredible amounts of energy, scientists have puzzled over what could be producing these powerful clusters of ...

A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...

Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles ...

High energy astrophysics probes the most energetic phenomena in the Universe, from explosive supernova remnants to the powerful outflows near compact objects. A central focus of this field is the ...
