Stars do not live for ever. New stars are made all the time, and old stars die, in the most amazgin ways.
In every galaxy, there are large clouds of gas, called nebulae, new stars are born, There are small stars, middle-sized stars, and very large stars. Some of these large stars are a hundred times bigger than our Sun. These big stars do not live very long- only about ten million years- but their short lives are very exciting.
