Scientists: All gold on Earth was forged from ancient collisions of dead stars

It was thought that gold was created in a supernova explosion, but new research points to a different stellar process involving the collisions of dead or neutron stars that occurred long before the solar system existed.

Scientists say they have fresh evidence of the ancient collisions after telescopes recently detected a strange glow in a distant galaxy. 

Astronomers have long known that lighter elements such as carbon and oxygen are created within a star. 

The new work was led by Harvard-affiliated researchers and will appear in a future issue of the Astrophysical Journal Letters.
