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 gamma rays hit molecules in the Earth’s atmosphere, they create a cascade of lower energy particles, and these can interact with the water molecules in those big tanks. Sensitive instruments keep ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

A Black Hole May Have Eaten a Star and Produced the Longest Gamma-Ray Burst Ever Recorded ...

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 ...

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 ...

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 ...

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 ...

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 ...

Gamma-ray bursts are the most luminous explosions in the universe, allowing astrologists to observe intense gamma rays in short durations. Gamma-ray bursts are classified as either short or long, with ...
