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

The world's first-ever detection of two faraway neutron stars colliding, causing a massive blast that rippled through the fabric of space and time, is judged the scientific breakthrough of 2017.

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 ...

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 ...

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, ...

Rochester Institute of Technology researchers played a significant role in an international announcement today that has changed the future of astrophysics. The breakthrough discovery of colliding ...

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, ...

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 ...
