Stars go through big changes in their lives, just like people do, from being born to growing old and even dying sometimes.
Stars are like giant balls of fire, burning bright in the sky. When they're young, they're very hot and shiny, kind of like a brand-new light bulb. They use up food (called fuel) to stay bright. This fuel is called hydrogen, and it's like the stars' favorite snack.
What happens when they grow old?
As stars get older, they run out of their favorite snack, hydrogen. Then they start eating something else, called helium. This makes them bigger and cooler, kind of like a balloon that gets bigger as it fills with air.
Sometimes, when the stars get really old, they puff out their sides in a big sneeze, sending out bubbles of gas, this is called a red giant phase. Then, after all that, some stars become tiny and cool, while others explode into supernovas, lighting up space like fireworks on a dark night.
