Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

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

The mysterious 10-second flash of energy, first detected in March, has been identified thanks to NASA's ever-impressive James ...

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

Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

SN Ares might be the most exciting one. The star exploded when the universe was about one-third of its current age.

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