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, ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...

Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed “superkilonova.” ...

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

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star explodes twice in violently different ways. Their analysis of a series of ...

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe. This breakthrough in nuclear physics shows explosions on neutron stars.

The world's first-ever detection of two faraway neutron stars colliding, causing a massive blast that rippled through the fabric of space and time, is judged the scientific breakthrough of 2017.

It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...

Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...
