Deep in the cosmos, an enigmatic object emits gamma rays at energies more than 100 TeV, an intensity far beyond what we typically observe. Discovered in 2021 by the Large High Altitude Air Shower ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.

Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO ...

Earlier this year, it was reported that 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 in ...

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 ...

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 ...

Scientists using the H.E.S.S. observatory in Namibia 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 ...

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 ...

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 ...
