Story summary

A NASA supercomputer simulation reveals chaotic interactions of neutron stars before their merger.
Neutron stars form from massive stars and have extreme densities and magnetic fields.
As two neutron stars orbit, gravitational waves tighten their orbits until they collide.
The collision produces gamma-ray bursts and heavy elements such as gold.
The team led by Dimitrios Skiathas, lead researcher, finds magnetic fields strongly affect radiation in this phase.
