For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

Too much cosmic radiation can sterilize a planet – but a surprising new study has found that under the right circumstances, it could actually make uninhabitable worlds habitable. Ionizing radiation ...

From 19 to 22 January, 80 particle physicists, astronomers and cosmologists gathered at CERN for the first “All that ...

Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...

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 ...

Deep in the cosmos, an enigmatic object emits gamma rays at energies more than 100 TeV, an intensity far beyond what we typically observe. Discovered in 2021 by the Large High Altitude Air Shower ...

An international team of scientists, led by the University of Oxford, has achieved a world-first by creating plasma "fireballs" using the Super Proton Synchrotron accelerator at CERN, Geneva, to study ...

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting. NASA primed for March launch of Artemis ...
