Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark ...

(a)The UHE gamma-ray emission is clearly observed from the W51 complex, which hosts the supernova remnant W51C and star forming region W51B. (b) The “bending” feature around tens TeV indicates the ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...

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 ...

The Einstein Probe satellite recorded a violent X-ray flare on 2 July 2025, catching what researchers now describe as a white ...

The James Webb Space Telescope has identified the earliest known supernova, a star that exploded when the universe was roughly 730 million years old. The discovery traces back to March 14, 2025, when ...

An X8.2 class solar flare flashes in the edge of the Sun on Sept. 10, 2017. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 304 angstrom ...

A new IAEA coordinated research project (CRP D12015) will apply gamma-ray spectrometry and digital technologies such as drones, satellite imagery and advanced analytics for precise soil assessment to ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
