Is the energy released by the stars a result of fission reactions?

No. However, the stars do use a different form of nuclear energy, called nuclear fusion or fusion.
In fission, heavy elements such as uranium are broken down into smaller elements, releasing huge amounts of energy in the process. This is used in power plants on Earth and was used in the first nuclear bomb dropped on Hiroshima, Japan.
In fusion, however, light elements starting with Hydrogen, the most abundant element in the Universe, are actually fused together into heavier elements such as Helium. Stars use this because there is SO much Hydrogen in the universe, and stars are full of it. Fusion requires a tremendous amount of energy to kick-start, but in return an even more tremendous amount of energy is released. That is what powers the stars. Currently, it is believed that elements up to oxygen (8) exist in our Sun.

How is a nuclear fission reaction controlled in a nuclear reaction?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
How is a nuclear fission reaction controlled in nuclear reactor?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
What is nuclear fission's result?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.
What is an easy description for fission?
In nuclear fission, a very large nucleus such as a uranium nucleus breaks apart into two smaller nuclei, and some energy is released as a result. If you can get a whole lot of heavy nuclei to undergo fission at the same time, the result is an atomic bomb.
What Equation involves nuclear fission and nuclear fusion?
Involving fission & fusion at the same time? These reactions are completely different from each other and have no physical or mathematical relationships. I suppose you could claim that a hydrogen bomb that uses a fission trigger is an example of such an equation, however, the fission occurs before the fusion, so they are still separate and distinct from each other. The mass-energy equivalence equation, E=mc^2, is used to calculate the energy released due to the missing masses found in the fission or fusion calculations, but it comes at the end to convert the mass result into energy only.

How is a nuclear fission reaction controlled in nuclear reactor?

How is fission used to calculate the energy required?
You don't use fission to do the actual calculation. Fission can RESULT in energy being released, though.

What is the definition of necular energy?
Atomic energy is released during a nuclear reaction during fission or fusion. It is released by the nucleus of an atom and can also be a result of radioactive decay.

Where in space do fission and fussion reactions happen and what is the result?
Fission and fussion manly occar in a star or a sun. The reason that a star or a sun is bright is because of the heat that is given off of from fission and fussion.
Why does not law of conservation of energy apply to the nuclear reactions?
A percentage of the matter is liberated as energy. Fusion reactions tend to convert more mass to energy than do fission reactions. Proton and neutron counts are preserved, but the mass of a helium nucleus is less than the rest mass of the particles of which it is comprised--two neutrons and two protons. The difference is known as the "mass defect," and is equivalent to the energy released in a fusion reaction. Similarly, fission reactions (the splitting apart of atomic nuclei) also liberates energy in a variety of forms. Note: Mass/Energy is conserved in ANY reaction. But as mass may be converted into energy, and vice versa, the mass itself is not necessarily conserved.
What is Alternative energy source produced from atomic reactions?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.
When fission is not controlled how is it used?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
Is nuclear fission a result of the suns energy?
No -> NASA doesn't mention that at all.
