A star’s lifetime is millions to billions of years, so witnessing the death of one is truly an exciting moment. Earlier this year, astronomers found evidence of a binary star system that will eventually create a kilonova, or an explosion that is thought to produce bursts of gamma rays and large amounts of gold and platinum. The system is home to a neutron star and a massive star that is in the process of going supernova, at which point it will also become a neutron star. Eventually, those two neutron stars will collide, producing the kilonova.
