LOS ANGELES (July 17, 2013)--Scientists say they have new evidence that all the gold on Earth was forged from ancient collisions of dead stars.
Telescopes recently detected a strange glow in a distant galaxy that researchers say came from the collision of dead stars.
Astronomers have long known that lighter elements such as carbon and oxygen are created within a star, but that process doesn’t produce heavier elements such as gold.
Experts thought gold was created in a supernova explosion, but the new research points to a different stellar process involving the collisions of dead or neutron stars that occurred long before the solar system existed.
The new work led by Harvard-affiliated researchers will appear in a future issue of the Astrophysical Journal Letters.
