Scientists have announced the discovery of nearly 300 gamma ray pulsars. The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to ...

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. When you purchase through links on our site, we may earn an affiliate ...

On Oct. 9, 2022, the sky was illuminated with a spectacular display of light when the brightest gamma-ray burst ever witnessed in history, GRB 221009A, occurred. The event was visible to the naked eye ...

Gamma irradiation of food is a simple, reliable, and mature technology. However, more use of alternative irradiation technologies, based on electrically generated sources, would help complement the ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

The positions of the cataloged pulsars shown in a top-down view of the Milky Way. The red and orange symbols indicate millisecond pulsars, while the green and blue symbols indicate young, unrecycled ...
