STARS By Luca L'Eveille. Introduction Stars are balls of gas mainly hydrogen and helium. Many stars are made up of the same elements on Earth even though. - ppt download

Stars are born out of clouds of gas and dust. As the star reaches middle age it shines steadily, powered by the hydrogen in the centre of the star. All stars no matter what size all run out of hydrogen and begin to die. Small stars live up to 200 billion years, medium stars live up to 10 billion years and large 10 million years. Our sun is medium sized, and has 5 billion years left to live. Birth and age
