"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of ...

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 ...

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 ...

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major ...

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 ...

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

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 ...

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 ...
