The difficulty with this, they explain, is that while lightning radio frequency signals can be mapped using ground sensors from any direction, the cosmic rays cannot. Instead, they could come from ...

Cosmic rays, high‐energy particles from extraterrestrial sources, continuously bombard the Earth, providing a natural probe of astrophysical processes. When these particles interact with the ...

New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from?

Nearly a decade ago, a detector searching for ghostly cosmic particles found two anomalous signals in Antarctic ice. But scientists haven’t been able to find anything similar.

If these particle detectors observe cosmic-ray showers simultaneously with our BIMAP sensors, then we’ll have confirmation of our observation that cosmic-ray showers seem to trigger lightning.

Scientists are trying to solve a decade-long mystery by determining the identity of anomalous signals detected from below ice in Antarctica.

A rare and extraordinary event has been captured by researchers in Japan, revealing that lightning on Earth can produce gamma-ray bursts—high-energy emissions typically observed from cosmic phenomena ...
