When do pirates hunt for cosmic gold? During the arrr-process. When two neutron stars merge, they produce heavy elements like gold in r-process nucleosynthesis. We use NASA - National Aeronautics and Space Administration missions to spot gamma rays emitted by these sources. #NationalTalkLikeAPirateDay | NASA Universe
