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.

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.

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It ...

On July 2, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

When a stone sits on the Earth’s surface, cosmic rays quietly pepper it, leaving behind rare isotopes like tiny time stamps.

Astronomers have made a historic discovery by directly detecting cosmic rays deep inside a dense, starless molecular cloud.

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

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove ...
