All stars eventually run out of fuel and die. Most fade away quietly, but the most massive stars self-destruct in a huge explosion that can outshine an entire galaxy.
Like Earth, stars generate the force of gravity which squeezes their hot core. The more matter a star has, the greater the force of gravity and the hotter and denser the core becomes. The way a star dies depends on how powerfully its core is squeezed by gravity.
Stars make heat and light by the process of nuclear fusion: hydrogen atoms in the core crash together to form helium, releasing energy. In small stars, when hydrogen in the core runs out, the stars light slowly fades. But in more massive stars, the core is so hot and dense that fusion can spread beyond it, changing the star's appearance. The most massive stars are eventually overwhelmed by their own gravity, which crushes them so violently that they collapse into a pinprick to a create a black hole.
Ways to die:-
Stars can die in four different ways, all of which are shown on these pages. Our Sun, a typical star, will follow the central path, but not yet - it has enough fuel to keep shinning for 5 billion years. When larger stars die, they turn hydrogen into heavier chemical elements such as carbon and oxygen, which are later recycled to form new stars and planets. All the atoms in your body were created this way.
