New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.

IN his article on the isotropic gamma ray background, Cheng 1 presents instructive calculations of the production and propagation of inverse Compton gamma rays in an expanding universe. The latter ...

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block.

Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright ...

In a recent study, scientists found that some portions of the sun emit more intense gamma ray radiation than others.

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

Gamma-ray burst charged Earth’s ionosphere from 2 billion light-years away The brightest supernova ever detected altered the outer layers of Earth's atmosphere.

Insight -HXMT is China’s first X-ray space telescope which is designed to observe the X-ray source in the Milky Way. However, it was extended to monitor gamma-rays in all-sky especially GRBs.

Scientists have pinned down the energy produced by an unusually bright gamma-ray burst detected in 2022, and wow is it a whopper.

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.
