The nuclear source of the sun's energy is hydrogen fusion. When the last of the
remaining hydrogen is fused into helium, the sun will start fusing the resulting elements until it hits iron, at which point the fusion reactions will end. Larger stars will go farther down the Periodic Table before blowing themselves apart.
It is fusion of hydrogen to form helium
The primary source of the sun's energy is nuclear fusion. This process occurs in the sun's core, where hydrogen atoms combine to form helium, releasing vast amounts of energy in the form of light and heat.
Nuclear fusion. Mainly, hydrogen-1 is converted to helium-4.
Nuclear fusion of hydrogen into helium.
nuclear fusion energy
The sun crushes hydrogen into helium with its immense gravity. This makes light and heat. This is a nuclear reaction.

No -> NASA doesn't mention that at all.
