A neutron star is made of the most dense substance in the universe. The collision of two neutron stars is a phenomenal event, second only to that of two black holes. The gravitational distortions are massive.
Just before 2 neutron stars collided in the galaxy NGC 4993, they produced a hot, dense & expanding cloud of debris. Within this debris, large quantities of some of the universe’s heaviest elements were forged, including gold and platinum. 👀✨
