Cosmic rays without end
Article Abstract:
Cosmic rays strike Earth from space and it seems probable that most are produced in the remains of supernova explosions in our galaxy. Energetic cosmic rays with energies above 10(super19) electron volts appear to come from outside our galactic disk. Takeda and colleagues have reported on the number of cosmic rays at the highest energies. The Auger project is to set up a detector in Argentina which will map out the spectrum and arrival directions of cosmic rays above 10(super19) eV.

Knee-deep in cosmic rays
Article Abstract:
Cosmic rays originate from supernovae remnants. A study of the remnant of supernova 1006 confirm the long proposed view that cosmic ray ions and electrons with high energies are formed from supernova. Cosmic rays with energies below 1 GeV to above 10 to the 20th power are detected by satellites, air-shower detectors and balloons. Collisions of unknown particles with air molecules produce high energy events at the top of the earth's atmosphere.

No-so-cosmic rays
Article Abstract:
Energetic particles, or cosmic rays, continually hit Earth and it has been assumed that their flux is roughly similar throughout the Galaxy. However Anatolya Erlykin and Arnold Wolfendale have published new data, using air-shower experiments, which shows that much of the cosmic-ray flux at Earth could come from a recent, close super-nova.
