Scientists find record high-energy cosmic ray electrons, but origin remains elusive

The Earth is under constant bombardment from cosmic rays, consisting mainly of protons and electrons, with origins linked to cosmic phenomena like supernovae and neutron stars.

The steady influx of cosmic rays, predominantly protons and electrons, enables scientists to unravel the mysteries of high-energy impacts and their cosmic sources.

Since the 1930s, scientists have been unraveling the complexity of cosmic rays, which have particle cascades hitting Earth's surface, offering insights into the universe.

High-energy electrons cannot travel far due to scattering effects in space, indicating their creation likely occurs within our nearby cosmic neighborhood.
