New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from? Cosmic rays—high-energy particles ...

NASA’s Chandra X-ray Observatory catalog provides over 400,000 sources and detailed X-ray mapping of the Milky Way center, ...

Every second, without you knowing it, thousands of billions of invisible particles pass through your body. These cosmic objects travel across the Universe from distant sources, moving at prodigious ...

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

Cosmic rays, high‐energy particles from extraterrestrial sources, continuously bombard the Earth, providing a natural probe of astrophysical processes. When these particles interact with the ...

Min Read Like a recording artist who has had a long career, NASA's Chandra X-ray Observatory has a "back catalog" of cosmic ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...
