The first gamma-ray bursts were discovered by accident in the 1960's, by spy satellites looking for gamma-rays from secret nuclear bomb tests.

A Self-Guided Tour of the Electromagnetic Spectrum Gamma rays It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one ...

During their quest to find the source of one of the brightest and most powerful explosions in the universe, astronomers discovered a new chaotic way that stars can die. The bright flash of gamma ...

Earth just got zapped. On Sunday a gamma-ray burst (GRB), the most powerful class of explosions in the universe, caused a wave of gamma rays and X-rays to sweep over Earth.

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and emit "x-rays and gamma rays (magenta)," according to NASA's Goddard Space ...

Long-duration gamma-ray bursts (those lasting more than a couple seconds) are related to the deaths of huge stars, those at least 20 times as massive as our sun and which are low on heavy elements.

There are two types of gamma-ray bursts: short and long. Classic short-term GRBs last less than two seconds, and they were previously thought to only occur from the merging of two ultra-dense ...

Gamma ray optics: a viable tool for a new branch of scientific discovery Date: May 4, 2012 Source: Institut Laue-Langevin (ILL) Summary: There has been a surprise discovery of ‘significant ...

Delayed gamma rays from deep space may provide the first evidence for physics beyond current theories. The MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope found that high-energy ...

Space Gamma ray bursts could help unravel how fast the universe is expanding It may be possible to use the brightest events in the universe, gamma ray bursts, to measure cosmic distances – which ...
