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

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

The final stage of a superkilonova. 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, ...

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

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

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

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 ...

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 ...
