Ultra-high energy cosmic rays are orders of magnitude more powerful than the sun's energetic particles: They can reach up to 10 20 electron volts, whereas particles from the sun can reach up to 10 ...

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

James (Jim) Cronin also devoted the second half of his career to studying cosmic rays. He conducted an experiment known as the Chicago Air Shower Array (CASA), which ran from 1992-1999 in Utah to ...

Although scientists have known about Ultra-High Energy Cosmic Rays (UHECRs) for years, nobody can pinpoint their origin. When these UHECRs hit the ground, however, they cause a widespread local ...

Artist’s illustration of ultra-high-energy cosmic ray astronomy to clarify extremely energetic phenomena in contrast to a weaker cosmic ray that is impacted by electromagnetic fields.

These ultra-bright high-energy X-rays can be used to image and study extremely dense matter, like the plasmas created during inertial confinement fusion. The team's work was recently published in ...

Generated when high-energy particles in space strike the atmosphere above Earth, muons have been used to monitor magma movement in a volcano, detect empty cavities in the Great Pyramid of Giza in ...
