Astronomers have found evidence which suggests that most of the universe’s gold was created during the collision and merger of two neutron stars.

Astronomers have found evidence which suggests that most of the universe’s gold was created during the collision and merger of two neutron stars.

A binary of two neutron stars will eventually spiral into each other. When they do, scientists believe that their violent merger produces short gamma ray bursts (GRB). Observations of a short GRB burst in June found a lot of spectroscopic evidence of gold.

[T]he explosion had been responsible for the creation of a whole menagerie of heavy elements. They estimated that an equivalent of 1% of the sun’s matter was being flung out from the collision in a tail, and about 10 parts per million of that tail was made of gold.
