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.

A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...

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, ...

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.

A strange double flash in a distant galaxy has given astronomers their strongest hint yet that a long‑theorized kind of ...

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

This is unreal. The post Astronomers Appear to Have Caught a Star Splitting In Half, With Catastrophic Results appeared first ...

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) ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...
