The Life of a Star
... This is what makes a star begin to die. As the hydrogen in its core is changed to helium, the hydrogen begins to run out, like the gas in a car. At this point, the star is not making as much heat as it used to, so the core starts having trouble holding its shape, and it begins to get smaller. While ...
