Stars are born and die from "summary" of A Short History of Nearly Everything: Special Illustrated Edition by Bill Bryson
Stars are colossal, glowing balls of gas that have an immense impact on the universe. They are not eternal; they are born and they die. The life cycle of a star is a complex and fascinating process that spans billions of years. Stars are born from massive clouds of gas and dust known as nebulae. Gravity causes these clouds to collapse and condense, forming a dense core. As the core becomes denser, pressure and temperature increase, leading to nuclear fusion. This fusion process releases an enormous amount of energy, causing the star to shine brightly. During its main sequence phase, a star will burn hydrogen at its core, converting it into helium. This process generates the energy that sustains the star and allows it to shine. However, stars are not immortal. Eventually, they will exhaust their hydrogen fuel and enter the ...
