The Solar Core

The center of the Sun is called the core. The core is made up of a really hot gas (in the plasma state). The temperature in the core is 15 million kelvins ! That's REALLY HOT!

The core is where the energy of the Sun is made. Things are just right for nuclear fusion reactions to take place. These reactions release energy in two forms, light and particles (in particular neutrinos).
