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 ...

Astronomers appear to have caught a star splitting in half, with catastrophic results
This is unreal. The post Astronomers Appear to Have Caught a Star Splitting In Half, With Catastrophic Results appeared first ...
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, ...
A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...
A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of colliding neutron stars known as a kilonova. Then it brightened again, shifted ...
Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe.
Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...
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 ...
Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron ...
