Yes, nuclear fusion
No. The sun is powered by nuclear fusion.
Yes, it is
thermonuclear fusion
Because thats the part of its life cycle it is now in.
The Sun is powered by nuclear fusion which requires extremely high temperatures to happen. Hydrogen is fused into helium releasing incredible amounts of energy which is counteracted by gravity.
The sun is powered by nuclear fusion, in which hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. This energy is what provides the light and heat that we receive from the sun.
"Why are you a nuclear powered human being?"
The sun is not burning like a true fire. It is powered instead by nuclear fusion, which uses hydrogen.
The first nuclear powered submarine was the USS Nautilus.
Everything, so to speak, is nuclear powered, because everything ultimately gets its energy from the Sun, and the Sun's energy is fusion nuclear power. This includes the food we eat and the raw materials we are made of.
Stars are powered by nuclear fusion
The sun is powered by nuclear fusion, and the resulting hot material in the sun and specifically on its surface radiates visible light along with other frequencies.
