Stars are formed as a result of a large cloud of gas and dust coming together to form a nebula. As additional particles combine with the nebula, it's gravitational force increases. This increase in gravitational force pulls the particles closer together, and as the particles are pulled closer together, the temperature inside the nebula increases. (It is known that the center of the earth is a hot matter, probably molten liquid. This is caused by the tremendous pressure and resulting heat in the center of the earth as well as the gravitational pull.) Stars are much larger than the earth so the gravity is significantly greater and more pressure is generated. This enormous pressure results in very high temperatures being generated. When the center of a nebula reaches a temperature of 10 million Kelvin (10,000,000K), fusion begins. The fusion reaction releases energy and a star is born.

∙ 14y agoWhen the sun was created, it was a ball of helium. It then grew so hot, the atoms of helium started to fuse. All stars do this to maintain 'life'. As the star fuses these helium atoms, they form hydrogen atoms, which are heavier. This is the main part of their lifespan. Then, when they start to die, they have run out of helium and start fusing hydrogen, which causes them to expand. Then, they eventually die. Our sun will live through a couple more billion years before reaching this stage.

Where in the universe does fusion occur naturally?
Nuclear fusion is the process that powers stars, such as our sun.
Does nuclear fusion occur in the sun's corona?
No, while it is hot enough the pressure is too low.
What process inside the sun is responible for producing it visible light?
Nuclear fusion. A by-product of nuclear fusion is energy given off, that we see as visible light.
What takes a extremely long time to occur inside the sun?
Fusion. Apex
What is the site of nuclear fusion on the sun?
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
It takes an extremely high temperature for nuclear to occur inside the sun?
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
Fusion reactions on the sun?
yes nuclear fusion does occur on the sun, creating intense heat and light
Where does most nuclear fusion occur in your solar system?
Sun
Where in the universe does fusion occur naturally?
Nuclear fusion is the process that powers stars, such as our sun.
How is it that radioactive decay has always warmed the earth from the inside and nuclear fusion has always warmed the earth from the outside?
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
How does nuclear fusion occur in the sun's interior core?
High temp and pressure
Nuclear reaction taking place inside sun is called?
Nuclear fusion; hydrogen into helium.
What layer of the sun does nuclear fusion occur?
It has to be at hundreds of millions of degrees kelvin, before a fusion reaction between deuterium and tritium will start
Why only in the sun's core does nuclear fusion occur?
The rest of the sun is too cold and too low pressure.
Does nuclear fusion occur in the sun's corona?
No, while it is hot enough the pressure is too low.
What process inside the sun is responible for producing it visible light?
Nuclear fusion. A by-product of nuclear fusion is energy given off, that we see as visible light.
How sun produces light?
The energy which produces light and heat in the Sun comes from "nuclear fusion" deep inside the Sun.
