SINCE 1928 I have been carrying out experiments on the absorption of cosmic rays in Lake Constance, which is 250 m. deep and lies 395 m. above sea-level. I was able to follow the cosmic rays to a ...

Astronomers measure cosmic electrons at the highest energies to dateThe starting point of the analysis is the measurement of the spectrum of cosmic rays, i.e., the energy distribution of the measured electrons and positrons. The analysis is based on 10 years of ...

New research on 'Death Star' that looks like a cosmic pinwheel reduces gamma-ray burst threat to EarthPrevious research also indicated that Earth looks down the axis of this system, known as Wolf-Rayet 104, raising concerns ...
XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...

What’s a muon? The Earth is under constant bombardment from cosmic rays, most of them being nuclei expelled from supernova explosions. As they collide with nuclei in our atmosphere, pions and ...
which in turn generate a spectrum of electrons and positrons hard enough to achieve the PAMELA and ATIC signals, while safely avoiding the overproduction of cosmic-ray antiprotons. To accommodate ...
