Cosmic-ray particles with the highest energies could give us clues about the mass of the relic particles from the Big Bang with the lowest energies - neutrinos - according to recent research.
Read article 'Remnants reveal origins of cosmic rays'
In the 90 years since the discovery of cosmic rays, there have been many theories about their origin, but little experimental evidence for actual sources.
Read article 'Debate sparked on quark stars'
Recent observations of two neutron stars have led to the announcement that a new form of matter might have been found. Astronomers using NASA’s Chandra X-ray observatory claim that one of the st...
