Quick Answer
A kilonova is a bright explosion created when neutron stars merge. It is powered by radioactive decay of heavy elements formed in the event.
The Full Story
A kilonova is an astronomical transient that follows the merger of neutron stars, or sometimes a neutron star and a black hole. The debris from the collision contains neutron-rich material where heavy elements are formed through rapid neutron capture, known as the r-process. As those newly made elements decay, they power a glow that can be observed across multiple wavelengths. The 2017 event associated with GW170817 provided strong evidence that kilonovae are major factories for some of the universe’s heaviest elements.
