Astronomers have found a space factory that creates pure gold

The merger of neutron stars is often called “kilonova”, by analogy with supernova. It is distinguished by the prohibitive energy of the process, as neutron stars possess monstrous gravity. When they merge, processes are triggered that allow long and complex pathways of formation of heavy chemical elements in a fraction of a second.
For example, data from the James Webb telescope allow us to speak with high confidence about the presence of the largest source of gold in the Universe at the site of neutron star mergers.
