Kilonova GW170817
NEUTRON STAR COLLISION · where gold is made
The first cosmic event ever seen with both gravitational waves and light. Two neutron stars spiraled together and collided, and in the radioactive fireball afterward, telescopes watched heavy elements being forged: gold, platinum, uranium, in quantities measured in Earth masses. The gold in any ring on your hand was almost certainly made in a collision like this.
