A combination of X-ray from NASA's Chandra observatory and radio data indicates that a galactic "fracture" was likely caused by a special neutron star called a pulsar.

The James Webb Space Telescope's ancient "little red dot" galaxies have been seen as a sign of "broken cosmology." Feeding ...

As cosmic rays push into these higher energy realms, they are less scattered by magnetic fields, making it easier to identify their original directions. Emerging evidence supports the idea that many ...

New insights into the origins of high-energy cosmic-ray electrons point to a mysterious source close to our solar system.

From its pristine vantage point on the International Space Station, the Calorimetric Electron Telescope, CALET, has uncovered anomalies in the spectra of protons and electrons below the cosmic-ray ...

The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin ...

Researchers at the Large High Altitude Air Shower Observatory (LHAASO) have accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 ...

The broad X-ray passband of HEX-P and superior sensitivity to NuSTAR will provide a unique opportunity to probe the evolution of AGN in extragalactic surveys over a wide range of obscuration regimes ...

The GRAPES-3 experiment in Ooty, India discovered a kink in the cosmic-ray proton spectrum at around 166 tera-electron-volt (TeV). The new feature will advance our understanding of the cosmic ray ...

The energy spectrum of cosmic ray nuclei around the cosmic ray knee reported in [18] . The knee energy of cosmic ray protons is indicated by the wide band around 2 PeV.
