What is a neutron star merger?

AstronomyGravitational Waves

Quick Answer

A neutron star merger happens when two neutron stars spiral together and collide. It can produce gravitational waves and a kilonova explosion.

The Full Story

When two neutron stars orbit each other, they slowly lose energy through gravitational-wave emission and eventually merge. The collision can create a spectacular kilonova, forge heavy elements such as gold and platinum, and release both gravitational waves and gamma rays. In 2017, the event GW170817 became the first neutron-star merger observed through both gravitational waves and light. That discovery gave astronomers a new way to study the origin of some of the universe’s heaviest elements.

Key Facts

1.Produces gravitational waves and often a kilonova
