Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and emit "x-rays and gamma rays (magenta)," according to NASA's Goddard Space ...

Scientists get closer to solving the mysterious relationship between lightning and powerful gamma-ray bursts.

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

Enhancing Gamma-Ray Spectrometry (GRS) technologies, integrated with digital and remote sensing technologies, for precise soil property determination and monitoring (e.g., texture, total carbon, total ...

The hole in the first-ever image of a black hole released a massive burp of gamma rays while astronomers were staring at it.

The Event Horizon Telescope, which captured the first image of a black hole, has done it again. The Earth-sized telescope spotted an unexpected explosion from the same supermassive black hole.

The origin of the cosmic diffuse gamma-ray (CDG) background in the $0.3-10 \\mathrm{MeV}$ energy range is a mystery that has persisted for 50 years. The best existing measurements have large ...

Below the knee Best-fit HAWC spectral energy distribution (pink) for HAWC J1746–2856 and (dashed purple) after subtracting the two HESS point-source spectra. The latter, which agrees well with the ...
