What happens in the area of the core of the sun?

In the core of the Sun, temperatures reach around 15 million degrees Celsius, creating conditions for nuclear fusion. Hydrogen atoms collide and fuse to form helium, releasing immense energy in the process. This energy is produced in the form of photons, which gradually make their way outward, contributing to the Sun's luminosity and heat. The core's fusion reactions are the primary source of the Sun’s energy, driving all solar processes.
