In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy ...

The afterglow of the study's subject, GRB 260310A, was one of the brightest observed in a decade.

Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the ...

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement ...

Faint, distant galaxies spotted by the James Webb Space Telescope are beginning to reshape how scientists understand the high ...

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 ...

New research has failed to rule out self-annihilating dark matter as the source of a gamma-ray emission radiating from the heart of the Milky Way.
