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 ...

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 ...

Fermilab’s Mu2e experiment has reached a critical assembly stage with its 60-ton cosmic-ray veto system in the detector hall, ...

The original version of this story appeared in Quanta Magazine. Of the 100 trillion neutrinos that pass through you every second, most come from the sun or Earth’s atmosphere. But a smattering of the ...

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

A major defense against everything space throws at us, Earth’s magnetic field may even protect the moon from damaging galactic cosmic rays ...

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 ...

Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in ...

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 dynamic, shifting cosmic environment.

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