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

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

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

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

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 ...

The discovery image that the Kilonova Seekers volunteers first saw of GOTO0650 when it went into outburst. The science, reference, and difference images are shown: the "science" image taken on the ...

Discover the fascinating phenomenon of superkilonova, a rare cosmic explosion resulting from neutron star collisions, producing heavy elements.
