Scientists have used a novel new approach to discover the potential origins of the sun goddess particle Amaterasu, the second ...

Scientists are exploring the origins of the Amaterasu particle, an extremely energetic cosmic ray first detected in 2021, which carries unprecedented energy levels.

Nearly 100 years ago, scientists detected the first signs of cosmic rays — subatomic particles (mostly protons) that zip through space at nearly the speed of light. The most energetic cosmic rays hit ...

New analysis by Francesca Capel and Nadine Bourriche narrows possible sources of the Amaterasu cosmic ray, suggesting nearby galaxies like M82 rather than the Local Void.

Francesca Capel and Nadine Bourriche analyze the most energetic particle that has ever hit Earth and its possible origin in ...

A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data ...

The origin of lithium (Li), the third element of the periodic table, has long been shrouded in mystery. This element, commonly found in cosmic rays as two stable isotopes, 6 Li and 7 Li, is crucial to ...
