The final stage of a superkilonova. 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, ...

Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

After detecting a strange combination of signals in the summer of 2025, astronomers believe they may have captured the first evidence of a unique phenomenon previously theorized, but never observed: a ...
