GRAPES-3 experiment researchers have identified a new characteristic in the cosmic-ray proton spectrum at an energy level of around 166 tera-electron-volt (TeV).
This is a finding that spans a measurement range from 50 TeV to just over one peta-electron-volt (PeV).
This observation introduces a potential shift in our understanding of cosmic ray origins, their acceleration processes, and how they move within the Milky Way.
Cosmic rays, discovered over a century ago, represent the universe's most energetic particles.
