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 ...
At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...
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 ...
In principle, cosmic-ray observations can provide detailed insights into the physical profile of a passing ICME. But despite ...
Cosmic ray air showers are produced when high-energy cosmic particles enter Earth’s atmosphere and interact with atmospheric nuclei, generating cascades of secondary particles. These extensive air ...
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 ...
The investigation of cosmic rays and their potential connection with dark matter occupies a central role in contemporary astrophysics. Recent experimental and theoretical advances have refined our ...
Star clusters are of great importance in any galaxy: they are the birthplace of new stars, often containing massive stars of 10 solar masses or more. Such massive stars often drive powerful winds; the ...
CC0 Usage Conditions ApplyClick for more information. Nearly 100 years ago, scientists detected the first signs of cosmic rays—subatomic particles (mostly protons) that zip through space at nearly the ...
