What is When a star exhausts its fuel?

A star is like a giant fire that burns for millions of years, but even fires need fuel to keep going.

Stars burn fuel, just like a campfire needs wood or logs. The fuel is hydrogen, and the burning process happens because of gravity pulling things together deep inside the star. When a star has enough fuel, it keeps shining bright in the sky.

But when that fuel runs out, like how a candle goes out when its wax is all melted, something changes. The star can’t keep burning anymore, so it starts to shrink and cool down. It becomes smaller and dimmer, like a fire that has turned into embers.

Sometimes, the star gets so big and bright before this happens that it blows off some of its outer layers, creating a colorful display in space, kind of like when you shake confetti from a bag!

This is what happens when a star exhausts its fuel, it changes shape, brightness, and even how it looks in the sky. A star is like a giant fire that burns for millions of years, but even fires need fuel to keep going.
