Two stars crash into each other, wobbling the universe and flinging out huge amounts of gold
The super-dense stars crashed together 130 million light years away, spewing out precious metals and other heavy elements like platinum and uranium – and experts say the event has kickstarted a "new chapter in astrophysics" and confirmed theories about the origin of the mysterious neutron stars.
Scientists didn't just "hear" the violent blast by seeing the ripples in spacetime. They were also able to use telescopes on satellites and the ground to see the light and radiation that was being flung out of the explosion, which is known as a "kilonova".
Analysis of the light revealed something astonishing – the manufacture of gold on a cosmic scale, as well as other heavy elements.
