How can a star die?
Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.
What is it called when a star dies?
Some types of stars expire with titanic explosions, called supernovae. When a star like the Sun dies, it casts its outer layers into space, leaving its hot, dense core to cool over the eons. A supernova can shine as brightly as an entire galaxy of billions of “normal” stars.
