A star is like a giant, glowing fireball in the sky that’s always burning.
Imagine you have a huge, super hot balloon, not just one, but billions of them all stuck together. That's kind of what a star looks like from far away. It's so hot inside that it shines brightly, and we can see it from Earth.
How stars work
Stars are made mostly of hydrogen, which is like the simplest balloon gas you can imagine. When these hydrogen "balloons" get squished together under extreme pressure, kind of like when you squeeze a toy until it squeaks, they start to fuse, or join together. This fusion makes new elements and releases lots of energy, like a giant light bulb turning on.
Why we see stars
Even though they're super far away, stars are so bright that their light travels through space and reaches our eyes. It’s like when you turn on a flashlight in a dark room, the light helps you see everything around you, even if the flashlight is way across the room.
Examples
- Stars are born from clouds of gas and dust, just like humans are born from mothers.
- When a star runs out of fuel, it can explode or shrink into something tiny.
