Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 ...

Astronomers have discovered a Great Wall in the universe that is so huge that it defies logic and cosmological principles. The Great Wall of Hercules-Corona Borealis is a galaxy cluster that runs for ...

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 ...

We utilize 14 years of Fermi -LAT data to set strong constraints on dark matter annihilation through a detailed study of the isotropic gamma-ray background, excluding with 95% confidence dark matter ...

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

Despite efforts using NASA’s Fermi gamma-ray space telescope and data from the H.E.S.S. observatory in Namibia, there’s only a faint whisper of gamma-ray emission from the region.

A thunderstorm seen in gamma-ray vision is a complex, frenetic lightshow when viewed from above the clouds.

In this work, the three-dimensional (3-D) position information of a radiation source is determined by a compact gamma ray imaging system. Two-dimensional (2-D) gamma ray images were obtained from ...

ABSTRACT: Gamma-ray bursts (GRBs) are the most intense and powerful explosions in the universe. Based on their observed duration, they are traditionally divided into long bursts whose observed ...
