The Sun is the star at the center of our solar system. It is a hot ball of glowing gases that emits vast amounts of energy, mostly in the form of light and heat. The Sun's energy makes life on Earth possible by providing the light and heat needed for plants to grow and for animals to survive.
The Sun's Structure
The Sun is made up of mostly hydrogen and helium. The core of the Sun is where nuclear fusion reactions take place, converting hydrogen into helium and releasing enormous amounts of energy. The energy from the core travels outward through the Sun's layers, eventually reaching the surface, called the photosphere.
The photosphere is the visible surface of the Sun that we see from Earth. It is a turbulent layer with bright, hot areas called granules and dark, cooler areas called sunspots. Sunspots are caused by disturbances in the Sun's magnetic field.
