The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

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

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 ...

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 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 ...

This artist's animation shows a hypothe sized event known as a superkilonova . Initially, a massive star explodes in a supernova, which generates elements like carbon and iron. In the aftermath, two ...

But it takes the collision of two neutron stars — incredibly dense stellar corpses — to create the heavier elements like silver, gold, and platinum. Neutron stars aren’t just notable for the valuable ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
