Galactic cosmic rays (GCRs) are mostly absorbed by Earth's atmosphere before they can reach the surface. However, they pose a ...

Barreling through the universe with incredible power and speed, galactic cosmic rays are a major source of radiation in space ...

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 ...

The findings, published in The Astrophysical Journal, provide fresh insights into ultraluminous X-ray sources (ULXs) — among the brightest and most enigmatic objects known in astrophysics.

A research paper described a region between Earth and the Moon where cosmic rays are deflected by our planet's magnetic field ...

Galactic cosmic rays from distant corners of the galaxy streak through your body -- as though you barely exist -- at nearly ...

A team of astronomers from the RRI has taken a closer look at one of the universe’s more puzzling phenomena that point to a ...

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 ...

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 ...

A new study using data from China's Chang'e-4 moon lander found an area of reduced radiation from cosmic rays near the moon.

Neutrino astronomy has emerged as a pillar of high-energy astrophysics following the discovery of a diffuse astrophysical neutrino flux by IceCube. The ...

In May 2021, an unusually high flux of cosmic rays bombarded Earth. According to a team of astrophysicists from the Raman Research Institute in Bengaluru and the University of Florida in the United ...
