Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes ...

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

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...

Wolf 359’s extreme radiation and frequent X-ray flares make life-sustaining atmospheres on nearby planets highly unlikely, ...

However, EP240408A refused to conform to what is expected of either of these powerful cosmic events, opening up the possibility that what the Einstein Probe actually saw with its X-ray eye was ...

Dr. Millikan recognized this ray ten years ago and called it the cosmic ray. He found that it penetrated 50 ft. of lead, 200 ft. of water. Last year Professor Auguste Piccard, cruising into ...

Nick Hague and Suni Williams spent six hours working on NICER, AMS and other equipment outside the International Space ...

Cosmic rays and their byproduct, muons, may help scientists study tornado formation by detecting pressure changes remotely. This technique would avoid the need for direct measurements within ...

Scientists have come a step closer to understanding how collisionless shock waves -- found throughout the universe -- are able to accelerate particles to extreme speeds. Scientists have come a ...

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a ...
