how the stars produce tremendous energy?

Answer 1

Thermonuclear reactions are the source of the energy in stars such as Sun. For example, in the sun nuclear fusion (two protons combining to form a helium nucleus, etc. ) produces the energy. However during some stages of the life of a star, gravitational contraction also acts an important source of energy.

Answer 2

It is the nuclear fusion that takes place in the stars which supplies the energy. Like in Sun the nuclear fusion takes place in between the hydrogen isotopes and Helium atoms are formed and a huge amount of energy is released.

H + T --> He + Energy

H = Hydrogen (atomic no. 1 and mass no. 1)
T = Tritium (isotope of hydrogen with atomic no.1, mass no. 3)
He = Helium (inert gas, atomic no. 2, mass no.4)

The same reaction takes place in Hydrogen Bomb(nuclear fusion), which is more powerful than Atomic bomb (nuclear fission).

Answer 3

The phenomona of stars, nova, supernova, quasars and gamma ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including of course solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen).


Dark energy is believed to make up 70% of the universeLight elements, primarily hydrogen and helium, were created in the Big Bang. These light elements were spread too fast and too thinly in the Big Bang process to form the most stable medium-sized atomic nuclei, like iron and nickel. This fact allows for later energy release, as such intermediate-sized elements are formed in our era. The formation of such atoms powers the steady energy-releasing reactions in stars, and also contributes to sudden energy releases, such as in novae. Gravitational collapse of matter into black holes is also thought to power the very most energetic processes, generally seen at the centers of galaxies .

Cosmologists are still unable to explain all cosmological phenomena purely on the basis of known conventional forms of energy, for example those related to the accelerating expansion of the universe, and therefore invoke a yet unexplored form of energy called dark energy to account for certain cosmological observations.

Answer 4

due to intense temperature,
two hyrogen nuclei fuse into a helium nucleus.this is called nuclear fusion.each such reaction can produce 8*10to the power 6 mega electron volts of energy.
imagine lakhs and crores of such nuclear fusion.

Answer 5

Nucular Fusion of Hydrogen atoms into Helium


*think of millions & millions of atom bombs going off every second.
