In a significant breakthrough, scientists have unraveled the mystery of cosmic rays, linking the ‘knee’ formation in their ...

For decades, a sharp kink in the energy spectrum of particles raining down from space has taunted astrophysicists, hinting at ...

Last week, an international team of over 400 researchers from 18 nations finally confirmed that high-energy cosmic rays are not coming from inside the Milky Way Galaxy, but instead from somewhere ...

Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high-energy cosmic ...

Kinky particles: the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. The inset shows the cosmic ray proton spectrum measurement by GRAPES-3 along with observations by ...

The origin of cosmic rays in the universe has confounded scientists for decades. But a study by researchers using data from the IceCube Neutrino Observatory at the South Pole reveals new information ...

Much astronomical research in the twenty-first century is a study of impermanence. Telescopes probing the full range of the electromagnetic spectrum, from radio waves to γ-rays, are unveiling an ...

This scientific figure of the cosmic ray energy spectrum, provided by researcher Bakhtiyar Ruzybayev at the University of Delaware, shows the steepening at the "knee." Below the knee, cosmic rays are ...

A direct determination has been made of the cosmic ray spectrum underground at a depth of 38 m.w.e. under Castle Rock, Nottingham. The spectrum is based on measurements of 1010 particles traversing a ...

Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...
