Stars are giant glowing balls that burn brightly for millions of years, but even they have to stop one day, just like how a candle goes out after some time.
Stars start their lives by burning hydrogen, which is like the fuel in a big fire. They keep shining bright while they have enough fuel to burn. But when the fuel runs low, things get interesting!
What Happens When a Star Runs Out of Fuel
When a star can't burn hydrogen anymore, it starts burning other stuff, like helium, which is like switching from wood to coal in your fire. This makes the star bigger and brighter for a while.
Eventually, the star runs out of fuel altogether. Then, it shrinks down and gets really hot inside, so much that it throws off its outer layers like a giant puffball letting go of cotton candy!
What’s left behind is a white dwarf, which is like a tiny, glowing ember that keeps shining for a very long time.
Some stars are bigger and end up exploding in a brilliant supernova, imagine a firework going BOOM! and lighting up the whole sky! Stars are giant glowing balls that burn brightly for millions of years, but even they have to stop one day, just like how a candle goes out after some time.
