How do stars grow and evolve over time?

Well honey, let me break it down for you. Stars start off as stellar nurseries, collapsing under their own gravity to ignite nuclear fusion. As they burn through their primary fuel source, they expand or contract based on their size until they eventually end their lives in a dazzling supernova or a more subtle white dwarf phase. It's a literal cosmic glow-up that would make even the Kardashians jealous.
