35 Facts About Neutron Star Mergers

What Are Neutron Star Mergers?

Neutron star mergers are among the most fascinating events in the universe. When two neutron stars collide, they create powerful explosions and release immense energy. These events can teach us a lot about physics, astronomy, and the universe itself.

1. Neutron stars are the remnants of massive stars that have exploded in supernovae.
2. They are incredibly dense, with a mass greater than the Sun but a diameter of only about 20 kilometers.
3. When two neutron stars orbit each other, they gradually spiral inward due to gravitational wave emission.
4. The collision of two neutron stars is called a kilonova.
5. Kilonovae are much brighter than typical supernovae but fade more quickly.
