Inside the heart of a star lies a powerful process that fuels the universe: nuclear fusion. Under immense pressure and extreme temperatures, hydrogen atoms fuse to form helium, releasing enormous amounts of energy. This process generates the heat and light we see from stars and keeps them from collapsing under their own gravity. Explore what happens deep inside a star’s core — where matter, energy, and gravity collide.
