Astronomers just tagged ultra-heavy atomic nuclei as the best suspect for the cosmos’s highest-energy rays — particles powerful enough to outpunch anything b…
On November 27, 2021, a detector array spread across the Utah desert recorded a single subatomic particle carrying about 244 ...
Scientists have discovered that ultraheavy atomic nuclei could explain some of the highest-energy cosmic rays ever observed.
High-energy cosmic rays, 10 million times more powerful than particles accelerated in Earth's strongest atom smasher, may hide a superheavy secret that is the key to unlocking a 60-year-old puzzle.
Ultrahigh energy cosmic rays may be made of nuclei heavier than iron, according to a May 2026 Penn State study in Physical ...
Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...
Scientists have detected changes in cosmic rays that could reveal the true origin of these extreme particles in the universe.
Francis Halzen obtained his PhD in 1969 from the University of Leuven, Belgium and is the Gregory Breit Distinguished ...
Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...
