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, ...

A strange cosmic blast that lit up the sky in two distinct acts is forcing astronomers to rethink how stars live and die. The event, tagged AT2025ulz, appears to be the first known case where a ...

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

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

The rare blast peeled back the inner layers of a dying star, offering clues to how the elements that make up life on Earth were forged. By Jonathan O’Callaghan Carl Sagan once said we are all made of ...

Kepler's supernova remnant is extremely exciting for astronomers – a rare example of a supernova for which we have a clear ...

Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, ...

Scientists have identified a never-before-seen supernova, SN2021yfj, which exploded after losing nearly all of its outer layers. Instead of light elements, it revealed silicon and sulfur from deep ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...
