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

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 Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a cosmic ray detector, was designed to measure the radiation environment in Earth ...

Researchers in the United States’ Fermilab moved the final subdetector for Mu2e into the ...

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

CERN's ALICE experiment has resolved the puzzle of deuteron formation, showing that most deuterons form via resonance-driven coalescence after collisions cool.

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), ...

An international research team led by scientists from the Technion – Israel Institute of Technology has achieved the first direct measurement of cosmic rays deep inside a star-forming nebula. Using ...

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

“It’s very slow, but over billions of years, it’s a very strong effect.” That is the main surprise of the observations of the interstellar comet 3I/ATLAS by the James Webb Space Telescope: the ...
