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

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

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron ...

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 ...

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.

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe.

Do we live in a supernova graveyard? A team of researchers proposes that 10 million years ago two giant neutron stars crashed into each other and debris from that intense explosion (called kilonova) ...

Merging neutron stars are excellent targets for multi-messenger astronomy. This modern and still very young method of astrophysics coordinates observations of the various signals from one and the same ...

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, ...
