Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...

Gamma-ray detection and analysis techniques have become indispensable in both basic and applied nuclear research. Modern systems utilise semiconductor detectors – notably high-purity germanium (HPGe) ...

For decades, astronomers have been puzzled by a mysterious glow of gamma rays emanating from near the center of the Milky Way. Two theories have emerged: either the light was the result of dark matter ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

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 ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

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 ...

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 ...

WASHINGTON, Oct 16 (Reuters) - Scientists may be coming closer to confirming the existence of dark matter - the invisible stuff thought to make up more than a quarter of the cosmos - as they study a ...

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, ...
