High-resolution radio measurements of air showers—cascades of secondary particles in the atmosphere initiated by cosmic rays—reveal that cosmic rays with energies of 1017–1017.5 electronvolts have a mixed composition, with light elements (protons and
For example, in work (Berezhko, 2009) the spectrum and mass composition of cosmic rays from supernovas located in the galaxy and beyond were calculated. The energy range 0.1–100 EeV is considered, and it is suggested that the detection of heavy cosmic rays composition at E0⩾10 EeV ...

Cosmic Rays are mysterious, high-charged atomic particles traveling through space at the speed of light. The rays have baffled scientists for years, but one political advisor believes the ability to see and study them could help generate interest in science and space among schoolchildren. Cao Bing...
Measurements of cosmic rays in past decades have revealed a break around 1 PeV in the energy spectrum, which is called the "knee" of the cosmic ray energy spectrum due to its shape resembling a knee joint. However, the origin of cosmic rays in the "knee" region is still an unsolved mys...

Galactic cosmic rays come from outside the solar system. They are a mixture of high-energy photons and sub-atomic particles accelerated toward Earth by supernova explosions and other violent events in the cosmos. Our first line of defense is the sun: The sun’s magnetic field and solar wind...
“When a cosmic ray happens to pass through the retina it causes the rods and cones to fire, and you perceive a flash of light that is really not there. The triggered cells are localized around the spot where the cosmic ray passes, so the flash has some structure. A perpendicular ray ...
