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

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 ...

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

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 ...

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 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 ...

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 ...

Sandia National Laboratories is planning a controlled explosives test near Kirtland Air Force Base on Wednesday, potentially ...

Caltech astronomer Mansi Kasliwal confronted a mystery blurring supernova and kilonova boundaries. 'Robbing them': Treasury slams states over Trump tax cuts Florida’s 'forgotten' coastline offers ...

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of ...
