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

Scientists have developed the longest and most complex simulation to date of a binary neutron star collision that results in the formation of a black hole and a jet. The breakthrough will massively ...

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, ...

"We do not know with certainty that we found a superkilonova, but the event nevertheless is eye-opening." When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star explodes twice in violently different ways. Their analysis of a series of ...

Merging neutron stars are excellent targets for multi-messenger astronomy. This modern and still very young method of astrophysics coordinates observations of the various signals from one and the same ...

Explosions of all varieties are booming throughout the universe. When a massive star dies, for instance, it bursts in a bright supernova, sometimes leaving behind a dead core called a neutron star.

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. A double blast of dying stars may be the first observed case of 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 ...

In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova. Reading time 3 minutes When massive stars die, they go out in fiery explosions called ...
