For years, physicists have wondered whether one unstable form of copper might act like a traffic jam inside some of the most ...

The most extreme fireworks in the universe are supposed to follow rules. Gamma-ray bursts, the brightest explosions known, are neatly sorted into categories, each tied to a familiar kind of cosmic ...

A single gamma-ray burst has forced astronomers to redraw their mental map of how the most violent explosions in the universe work. Instead of behaving like a textbook blast, this eruption stayed ...

A jetliner was nearly knocked out of the sky and sent plummeting to a deadly crash that would have killed all onboard by a bizarre attack from outer space – an explosive burst of cosmic rays sent ...

Gamma-ray bursts are a relatively new field in space science. The first was discovered in the late 1960s, and in the nearly six decades since, there’s never been a discovery quite like this. It may ...

Artist's rendition of GRB 250702B's ultra-relativistic jet (moving at nearly the speed of light) escaping from its dusty, massive host galaxy. Astronomers at the University of North Carolina at Chapel ...

Astronomers have caught the longest gamma ray burst ever seen, a seven-hour flash of high-energy light that looks like a black hole eating a companion star from the inside. The event, named GRB ...

Cosmic rays, high‐energy particles from extraterrestrial sources, continuously bombard the Earth, providing a natural probe of astrophysical processes. When these particles interact with the ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...
