From the New York Times:

This is the story of a gold rush in the sky.

Astronomers have now seen and heard a pair of dead stars collide, giving them the first glimpse of what they call a “cosmic forge,” where the world’s jewels were minted billions of years ago.

The collision rattled space-time and sent a wave of fireworks across the universe, setting off sensors in space and on Earth on Aug. 17 as well as producing a long loud chirp in antennas designed to study the Einsteinian ripples in the cosmic fabric known as gravitational waves. It set off a stampede around the world as astronomers scrambled to turn their telescopes in search of a mysterious and long-sought kind of explosion called a kilonova.
