What is Late-stage stellar evolution?

Stellar evolution is like a star going through different life stages, and late-stage stellar evolution is when it gets really old and starts to change dramatically.

Imagine your favorite toy that you’ve played with for years, it might start to fall apart or look completely different. That’s kind of what happens to a star in its late stage. After burning brightly for most of its life, it runs out of fuel and begins to grow bigger or shrink, depending on how big it was at first.

• Big stars become huge red giants, then they might explode in a supernova, scattering their stuff into space.
• Smaller stars, like our Sun, puff up into red giants and then shed their outer layers, leaving behind a tiny, hot core called a white dwarf.

It’s like the difference between a firecracker and a slow-burning candle, both are fun, but they end in very different ways. And just like how your toy might inspire new games, these changes help create new stars and planets in the future!
