How the Sun Really Shines

The sun doesn't actually burn like fire. Deep in its core, something way more

powerful happens. The sun squeezes hydrogen atoms together under extreme heat and pressure,

and when these atoms fuse, they release massive amounts of energy. This process is

called nuclear fusion, and it's what keeps our star shining bright without needing a single breath

of oxygen. No air required, just pure atomic power generating all the heat and

light that reaches Earth every single day.
