The Life Cycle of the Stars
... Like all stars, our Sun was formed from a cloud of hydrogen gas and dust that almost certainly included the ashes from an earlier star gone supernova. In its death throes, it created elements heavier than iron that our solar system inherited. Gravity pulled the cloud together into a giant ball. When ...
