Word of the day: kilonova

I’m endlessly fascinated by the size and complexity of the known universe. We seem to know so little and are regularly discovering new objects. So I know about the type of object called a supernova. But today is the first time that I’ve heard of a kilovova.

A kilonova (also called a macronova) is a transient astronomical event that occurs in a compact binary system when two neutron stars or a neutron star and a black hole merge.

You can read more about the recent discovery of one of these objects, and how it creates heavy elements, here.
