Are stars nuclear energy?
Stars produce nuclear energy by fusion Stars form when contracting dust in a planetary nebula contract and get so hot that nuclear fusion occurs. It explodes, forming a porotostar. Nuclear fusion of hydrogen atoms combining to form helium atoms is what keeps the star glowing.
Where in the sun is hydrogen fused into helium?
Hydrogen is fused into helium in the core of the sun, where temperatures and pressures are high enough to initiate nuclear fusion reactions. The core is where the sun's energy is produced through the fusion of hydrogen nuclei into helium nuclei.
Stars get there energy from?
Stars generally get their energy from hydrogen. By far the most common source of energy from a star (like our sun) is the nuclear fusion of hydrogen atoms into helium. As long as there is enough hydrogen, and other elements, to support the nuclear fusion, the process will go on. Therefore, stars generally get their energy from large amounts of hydrogen which coalesced during the star formation and through gravity received enough mass (weight) to start the nuclear process.
What are stars made of and What reactions keeps them alive?
Stars in our Milky Way are composed of about 71% hydrogen and 27% helium (mass) Thermonuclear fusion is what keeps the stars "shining", but this process is actually what leads to the eventual death of the stars. and in depth article can be found at http:/en.wikipedia.org/wiki/Star
When does hydrogen-helium fusion and helium-carbon fusion occur in stars like our sun?
When hydrogen stocks run out
What is a falled star?
Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain. Such stars are also known as brown dwarf stars.Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain.

What triggers nuclear fusion stars?
Fusion in stars are usually the result of gravity.Once a mass of hydrogen accumulates enough mass, the gravity of all that mass compresses the core of the star to the point that the hydrogen atoms there begin fusing into helium. The process then cascades outward, and the end result is a star.
What is the fuel that runs fusion in stars?
Initially it is hydrogen. When that is spent, stars move to fusion of helium. There are also other fusion processes which take place: which process depends on the stars' mass.

Hydrogen bombs and stars both produce energy with nuclear?
fusion reactions, where lighter elements combine to release tremendous amounts of energy. In stars, the fusion of hydrogen into helium powers their luminosity and heat. Hydrogen bombs use isotopes of hydrogen to trigger a controlled fusion reaction, releasing a massive amount of explosive energy.
What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
Why do you get stars?
Stars form because anything with mass has gravity. So Hydrogen eventually pull together and start compacting which releases intense heat and when there is enough Hydrogen the star will start the process of Fusion and are then as wee see them today.
