Answer 1

The energy from the sun comes from nuclear fussion: the combining of 2 Hydrogen atoms to make Helium and energy.
When the sun will lose it's fuel (in about 5 Billion years), it will turn into a red giant star.

Answer 2

The Sun produces an amazing amount of light and heat through nuclear reactions. The process that produces the Sun’s energy is called nuclear fusion. In nuclear fusion, two atoms come together to produce a heavier atom. Fusion reactions release energy and tiny elementary particles. The separation of hydrogen nuclei from their electrons makes nuclear fusion possible at the Sun’s core, producing the Sun’s light and heat. With their electrons gone, hydrogen nuclei (protons) can be packed much more tightly than complete atoms. At great depths inside the Sun, the pressure of overlying material is enormous, the protons are squeezed tightly together, and the material is very hot and densely concentrated.

The sun's life cycle evolution will involve dramatic stages of expansion and contraction as the sun approaches the end of its life cycle. After the sun has consumed the hydrogen in its innermost core, the core begins shrinking, converting hydrogen into helium in ever-larger shells around the inner core. The sun’s core will shrink because the outward pressure of heat generated by the nuclear reactions will no longer balances the inward gravitational attraction of the sun’s mass for itself.

Although the core of the sun will gradually shrink as it exhausts its hydrogen supply, the sun itself will begin expanding. It resorts to burning the hydrogen in a shell around its helium core, which will inflate the outer layers of its atmosphere. Eventually, the sun will expand into a red giant, possibly attaining a diameter from 10 to 1,000 times the diameter of the Sun. In its red giant stage, the Sun will expand to the size of the orbit of Earth or beyond and become 2,000 times brighter than it is now. The shrinking core increases the sun's internal pressure. The increase in pressure makes the sun's temperature will increase again until it is hot enough to trigger nuclear reactions between previously inert helium nuclei present in the sun. This new series of nuclear reactions releases more energy and the sun's core stops contracting. At this point, the sun's outer atmosphere will continue to contract.

Answer 3

The energy comes from the fusing of hydrogen into helium in the sun's core. As the hydrogen runs out, the helium starts to get fused into heavier elements.

In a few billion years when the available fuel runs out, the sun (which by this time will have puffed up to a red giant) will start to shring back down and fade, eventually becoming a brown dwarf. The sun isn't massive enough to explode as a supernova.

Answer 4

the energy of the sun is derived from continuous nuclear fission and fusion reactions taking place in it.everything has an end and so the energy of the sun also.i don't think we should worry about that end because it is estimated to last for another 500(50,don't remember correctly) million years.that is a long time and by then humans may destroy themselves or at least there will be no more life on earth.

Answer 5

the energy of the sun comes from the sun itself. inside it is produced a termonuclear reaction in wich 2 hidrogen nucleus fused to form an helius. as resul of this reactions, a high amount of energy is free as electromagnetic radiation. If one day the energy of the sun ends our planet will be frozen. i dont think that if the energy of the sun end the planet will survive, bcz before the end of the energy the sun will " eat" mercury, venus and the earth, so you wont see it!

Answer 6

im actually learning about the sun right now the energy of the sun comes from all the elements that the sun is made of...the elements in order are hydrogen-helium helium-carbon or oxygen carbon-neon or magnesium oxygen-silicon or sulfur silicon or sulfur-iron and with all those elements fusing together it creates massive energy

Answer 7

sun enegy comes from fusion of small hydrogen isotopes with heavy isotopes of hydrogen.in this reactiopn helium is produced by result of hydrogen's istopes fusion.and a little mass is converted to energy just like atom bomb but in atom bomb fuion of atoms not occure.
secondly that almost nothing will hapen to universe however solar system will destroy.earh life will finish as sun is only resorce of energy in solar system and you know that life is possible just by energy.and solar system will distroy as sun will also distroy & solar system is just due to sun.

Answer 8

It coems from nuclear fusion. It will end someday but it's a very slow process. WHen it is truly done, the earth will freeze.

Answer 9

If not before, you would die in 9 minutes.The Earth would be no more. Or any of the planets either.
