A flash of energetic light lasts only ten seconds, yet it has completely turned around our understanding of the timeline for ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

An international team of astronomers, working with researchers from University College Dublin and other institutions, has ...

James Webb has spotted the most distant supernova ever seen, exploding just 730 million years after the Big Bang, offering ...

The telescope captured near-infrared light from one of the earliest stars seen to explode in the history of the universe. (Nanowerk News) NASA’s James Webb Space Telescope has observed a supernova ...

Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a Program of NSF’s NOIRLab, astronomers ...

The mystery of dark matter could be solved in as little as 10 seconds. When the next nearby supernova goes off, any gamma-ray telescope pointing in the right direction might be treated to more than a ...

Artist's visualization of GRB 221009A showing the narrow relativistic jets — emerging from a central black hole — that gave rise to the GRB and the expanding remains of the original star ejected via ...

The universe doesn't always cooperate. Science has puzzled over gamma-ray bursts since they were first detected in the 1960s, and just when we think we have the basics solidified, something happens to ...

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 ...
