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 ...

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

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 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 ...

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 ...

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 ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

Talk about a heavy snack. For the first time, astronomers have witnessed a black hole swallowing a neutron star, the most dense object in the universe — all in a split-second gulp. Ten days later they ...

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 ...

It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...
