It was discovered about 100 years ago that if a star was just made of gas that is cooling naturally, it would shine for only a few hundred years. Stars were later found to contain mainly hydrogen and it was also discovered that fusion of hydrogen into helium would provide the energy to keep the stars shining for billions of years. So that's the theory.
What else can I help you with?
Is the sun nuclear powered?
Yes, nuclear fusion
Is the sun electrical?
No. The sun is powered by nuclear fusion.
What nuclear energy is the sun powered by?
thermonuclear fusion
Why is the sun powered by nuclear fusion?
Because thats the part of its life cycle it is now in.
How is the sun powered?
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.
Does fusion produce light?
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.
Name the nuclear process by which the suns is powered?
Fusion, as it is joining the nuclei of smalled atoms together to form another atom and a spare neutron and releases energy. In a main sequence star, such as our sun, it will fuse together the nuclei of the isotopes of hydrogen (deuterium and tritium) to form helium.
How is your sun powered?
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.
Is the sun a nuclear fusion reactor?
Yes, the sun is a nuclear fusion reactor.
How come the sun can survive in without oxygen?
The sun is not burning like a true fire. It is powered instead by nuclear fusion, which uses hydrogen.
What is the site of nuclear fusion on the sun?
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
Where does nuclear fusion take place in the sun?
Nuclear fusion takes place in the core of the sun.
