The mysterious origins of cosmic rays that slam into the Earth?s atmosphere could soon be revealed, thanks to a better ground - based sensor that costs less than balloons or satellites. (space.com)
One of the most pressing mysteries in astroparticle physics is the composition and origin of cosmic rays at energies around 1 EeV = 1018 eV. (auger.org)
The CTA, which should be completed by around the end of the decade, would allow scientists to carry out a range of research projects across astrophysics and fundamental physics, from the origin of cosmic rays to particle acceleration around black holes. (sciencemag.org)
