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 ...

Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

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

Caltech astronomer Mansi Kasliwal and her colleagues were not expecting to chase a mystery that blurred the line between a supernova and a kilonova. Yet that is where the evidence has led after an ...

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

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

A novel astronomical event, termed a "superkilonova," is proposed to explain the coincident detection of gravitational waves (S250818k), indicating a subsolar-mass neutron star merger, and an ...

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." When you purchase through links on our site, we may earn an ...

New research describes how a kilonova explosion triggered by colliding neutron stars could eradicate life on Earth for thousands of years. Thankfully, the odds are incredibly low. When you purchase ...
