Have you ever wondered about the stars？ In some ways， stars are like people. They are born， then grow old， and at last they die.
A star is born from dust and gas. Slowly the dust and gas make a ball. The ball gets very hot. Then it stars to give off light.
The young star grows into a giant. Many years go by. The older star begin to get small again. At last its light goes out. The star's life is over.
