Astronomers have spotted a cosmic explosion of high-energy gamma-rays unlike any ever seen before. The gamma-ray burst (GRB) designated GRB 250702B set itself apart from other explosive bursts of ...

It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

There is no strict theoretical limit on the highest energy of astrophysical gamma rays, so far as I know, but there are some practical limitations. The first is the energy of the particle that ...

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

The discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation. When you purchase through links on our site, we may earn an ...

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 cycle, a gamma-ray wave traveling at the speed of light will ...

DURHAM, N.C. — Duke University engineers have led the most detailed analyses of links between some lightning events and mysterious gamma ray emissions that emanate from earth’s own atmosphere. Their ...

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 ...

"Gamma rays can break every chemical bond [in a food's proteins, fats and carbohydrates] with gusto," says biophysicist Richard Piccioni, who works for Food & Water. The liberated molecules are free ...
