The life of the stars Stars could live for millions of thousands years. And the most of them seems not to change during a human life. Study their lives is like trying to study a forest in wich one there are trees of different types, ages and then try to investigate how grows every tree individually. As the trees, all the stars don’t get old in the same velocity. Stars similar as the Sun live about 10,000 millions of years, but a really giant star could live barely some millions of years. When a stars pass from a life stage to another, its shape change. Do you know that lots of the elements of the Universe, including that form our body, were made in the stars? Then these elements were mixed with the gas clouds that form other stars and planets. About the image of the Mystic Mountain: “Hubble's 20th anniversary image shows a mountain of dust and gas rising in the Carina Nebula. The top of a three-light-year tall pillar of cool hydrogen is being worn away by the radiation of nearby stars, while stars within the pillar unleash jets of gas that stream from the peaks.
