What happens to a large mass star at the end of its life cycle?

At the end of its life cycle, a large mass star undergoes a supernova explosion after exhausting its nuclear fuel. This explosion disperses the outer layers of the star into space, while the core collapses under gravity, potentially forming a neutron star or a black hole. The remnant can have a profound impact on its surroundings, enriching the interstellar medium with heavy elements and triggering the formation of new stars.
