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 ...

Gamma-ray bursts are the most powerful, brightest explosions in the universe. They last only seconds but release immense amounts of energy—as much, in fact, as the sun will emit throughout its ...

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind ...

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 ...

What is the nature of dark energy, a recently discovered dominant constituent of the universe today? Is expansion-accelerating dark energy an intrinsic property of space-time itself or rather a field ...

Artist's impression of a relativistic jet of a gamma-ray burst (GRB), breaking out of a collapsing star, and emitting very-high-energy photons. (Credit: DESY, Science Communication Lab) (CN) — With ...

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 ...

Scientists using the Milagro Gamma-ray Observatory in New Mexico have captured evidence of radiation emitted from the plane of our home galaxy at extremely high energies. The researchers detected “TeV ...

When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using ...

A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...
