Neutron star collision may have seeded the solar system with gold
In a new study, astronomers have found that a small fraction of all the gold on planet Earth was likely formed in a single, catastrophic, and very weird event: The merger of 2 neutron stars. The material blasted out from the ensuing explosion mixed with the stuff that formed the Sun and planets, and, eventually, us. Literally, you and me.
