About 135 million years ago, two sister stars started their dance of doom.
They orbited each other, spiralling closer and closer, faster and faster.
However, one of the sister stars ran out of fuel and died.
Still, the older sister continued to orbit her sibling, absorbing all the leftover gas into its own.
And so continued the dance, until one day, the older sister died too and two neutron stars were left, still orbiting each other in the after-life, until one day, they got so close together, they merged.
So ensued a killer nova explosion that sent gravitional shockwaves across the universe.
Some 135 million years later, on August 17, those shockwaves reached a part of space that eventually became Earth's home.
First, the waves were picked up by the Laser Interferometer Gravitational-Wave Observatory, also known as LIGO.
Astronomers around the world were alerted to what will now be known as one of the biggest astro-observations in recent history.
As the telescopes were pointed up, they saw what was left of the explosion, a pin-prick of light, visible for no longer than a second.
It's been debated for decades, but finally, we now know where gold came from. - the origin of that ring on your finger, perhaps the cellphone you're currently using to read this.
For the first time, scientists detected the collision of two neutron stars that sent platinium metals spiraling into space.
