Move over uranium, the Milky Way’s oldest stars have bigger and better elements to make.
A group of researchers from across the United States, Canada and Sweden have discovered ancient neutron stars might have created elements with atomic mass greater than 260.
With an atomic mass of 238, uranium is the heaviest naturally occurring element known on Earth, though others like plutonium have been found in trace amounts due to reactions in uranium deposits.
