　　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.
