What process is responsible for the production of tremendous heat of the sun?
Nuclear fusion, specifically the proton-proton (P-P) chain, is responsible for more than 98% of the Sun's energy. Less than 2% of the Sun's energy is estimated to come from the Carbon-Nitrogen-Oxygen Fusion Cycle, because the Sun is not massive enough to depend on the CNO cycle.
How is helium formed from hydrogen?
It's called the proton-proton cycle. It's the source of the sun's energy. Also called nuclear fusion.
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
Who discovered nuclear fusion in 1944?
Nuclear fusion occurs naturally in stars. Artificial fusion in human enterprises has also been achieved, although it has not yet been completely controlled as an energy source; successful nuclear physics experiments have been performed involving the fusion of many different nuclear species, but the energy output is negligible in these studies. Building upon the nuclear transmutation experiments of Ernest Rutherford done a few years earlier, fusion of light nuclei (hydrogen isotopes) was first observed by Mark Oliphant in 1932; the steps of the main cycle of nuclear fusion in stars were subsequently worked out by Hans Bethe throughout the remainder of that decade.

Does nuclear fusion occur at 15000000c?
It certainly can. It can also occur at lower or higher temperatures. 15 MK is roughly the core temperature of the Sun. At this temperature the PP chain is dominant, with the CNO cycle contributing roughly an order of magnitude less energy. At around 17 MK the two are roughly equal, and at higher temperatures the CNO cycle becomes dominant. Much below 4 MK, you're not normally going to get significant fusion (there are "cold fusion" techniques that can happen at much lower temperatures, such as muon-catalysed fusion, but these aren't net producers of energy: it takes more energy to make the muons than you can get out of the resultant fusion reaction).

Why is the sun powered by nuclear fusion?
Because thats the part of its life cycle it is now in.
What process does hydrogen changes to helium during a star's life cycle?
Nuclear fusion
How is helium formed from hydrogen?
It's called the proton-proton cycle. It's the source of the sun's energy. Also called nuclear fusion.
How did oxygen form on earth?
from nuclear fusion on the surface of the sun when it went nova, but it was also formed by plant life through the calvin cycle
How does nuclear energy relate to the sun?
We derive electromagnetic energy from the nuclear fusion reactions on the sun. We also apply nuclear energy (fission) on earth to generate lots of thermal energy, which we use in a steam cycle to generate lots of electric power.
Which nuclear reaction takesplace in sun?
Nuclear fusion takes place in our sun, specifically the proton-proton (p-p) chain variant of fusion. There is another variant, the carbon-oxygen-nitrogen (cno) cycle, which is used in much larger stars, and to a lesser degree, our own Sun (less than 2%).
