Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 exa-electronvolts. Its apparent arrival from a nearly empty region of space ...

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 ...

The study of cosmic rays and heliospheric physics bridges our understanding of high‐energy particles from distant astrophysical sources and the dynamic environment shaped by the solar wind and ...

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

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 ...

The study of cosmic rays, high-energy particles originating from extraterrestrial sources, has significantly progressed with the advent of both ground-based and space-borne detection techniques.

China’s Large High Altitude Air Shower Observatory (LHAASO), a major scientific infrastructure, has released groundbreaking results from its "Mini Survey of the Milky Way" program. With unprecedented ...

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 ...

Scientists are exploring the origins of the Amaterasu particle, an extremely energetic cosmic ray first detected in 2021, which carries unprecedented energy levels.

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...
