The Mystery of Ultra-Heavy Cosmic rays

Bedtime Astronomy

About
Researchers at Pennsylvania State University suggest that ultra-high-energy Cosmic rays may consist of ultra-heavy atomic nuclei beyond iron.

The idea could explain how extreme particles like Amaterasu retain enormous energy across deep space and may help scientists trace these mysterious signals back to violent cosmic events such as neutron star mergers and collapsing stars.
