Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.

A record-shattering stellar blast has been caught on camera in unprecedented detail, and the footage is forcing astronomers to rethink how stars die. The event, linked to an extreme gamma-ray outburst ...

Scientists may have to rethink their playbook for studying gamma-ray bursts, the most powerful known cosmic explosions, after a blast detected in July set a new record by firing energetic jets for ...

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting. Telescopes on Earth and in space — ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...

This artist’s concept depicts GRB 250702B (left of center) erupting within its host galaxy. This powerful explosion, first detected on July 2, blasted out narrow jets of particles at nearly the speed ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

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 ...
