All that glitters is not gold, they say. But all the gold in the world may come from astronomical events that send a lot of high-energy light out in space.

Researchers have new evidence that gold comes from the collision of neutron stars.

"We can account for all the gold in the universe from these collisions," said Edo Berger, astronomer at the Harvard-Smithson Center for Astrophysics. Berger spoke about these results, submitted for publication in The Astrophysical Journal Letters, at a press conference Wednesday.
