The Sun is composed mostly of hydrogen and helium, and it is so massive that its weight compresses the core to the point where there is sufficient temperature for nuclear fusion of hydrogen to occur. This fusion produces a collosal amount of energy, in the form of light, heat and solar radiation, and it also produces helium.
