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 ...

A giant explosion that lit up the sky didn't just rock the cosmos – it absolutely rattled our understanding of the Universe's most powerful outbursts. The gamma-ray burst (GRB) recorded on 2 July 2025 ...

A team of astronomers led by Matteo Cerruti of Paris Cité University reports multi-wavelength evidence for a repeating, roughly 3-year modulation in the gamma-ray output of the blazar S5 1044+71, a ...

Scientists have captured the first–ever direct evidence for dark matter, the elusive substance that makes up more than a quarter of the universe. Using NASA's Fermi telescope, researchers have ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

A gamma-ray burst is the most violent explosion in the universe. The research on gamma-ray bursts, including a central engine, magnetized dynamics of plasmas, and radiation, is one of the hot topics ...

Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Thunderstorms create a lot of wind, rain, and lightning, but many ...

Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin, researchers from The Australian National University (ANU) have confirmed. Lead ...
