The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

"This was many times more energetic than any similar event and more than any known explosion powered by the collapse of a ...

Something extraordinary happened near the end of the last Ice Age, when mammoths still roamed and early hunter gatherers were ...

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

Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.

Researchers at the University of North Carolina at Chapel Hill have contributed to new insights into the most long-lived cosmic explosion ever recorded. The event was a gamma-ray burst that remained ...

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

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 ...

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz—evidence of intense heat ...
