Earlier this year, it was reported that the Earth was hit by the brightest gamma-ray bursts seen since the dawn of civilization. Now, a team of astronomers has assigned a value to the energy contained ...

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The researchers think that infrared light particles (photons) from the poles of the pulsar are boosted to gamma-ray energies (blue) by fast electrons. Scientists using the H.E.S.S. observatory in ...

Astronomers using the James Webb Space Telescope report that a powerful gamma-ray burst detected in March may have been produced by the explosion of a massive star just 730 million years after the Big ...

Researchers have known for several decades that thunderstorms can act as miniature particle accelerators that produce antimatter, gamma rays and other nuclear phenomena. But they did not know how ...

Gamma-ray bursts are the most powerful explosions in the universe. They emit most of their energy in gamma rays, light which is much more energetic than the visible light we can see with our eyes. In ...

During a powerful solar blast March 6/7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the Sun. The discovery heralds Fermi’s new role as ...

"Maybe there are additional mechanisms generating gamma rays that go beyond the interaction of cosmic rays with the surface of the sun." When you purchase through links on our site, we may earn an ...
