stars generate their lights and energy by themselves from a process called Nuclear fussion,they use gasses like hydrogen as fuels to run this process.As they become older they begin to run out of their natural fuels,and begin to use heavier elements as its nuclear fuel.Eventually,iron forms in the core,preventing further fussion reaction.As the star shutsdown,it collapse in on itself and blows itself apart as a supernova.A supernova ends a stars life span.
