Strictly speaking nowhere in space, because space has no matter in it. Fusion happens in the stars. Fission may occur in some planets somewhere in the universe but not in our solar system

Is the nuclear reaction in the sun the same as in nuclear bombs?

In the so-called "hydrogen bomb" or fusion bomb, yes, there is energy released from the same reaction (hydrogen fusing to helium) as in the Sun.However, many if not most atomic bombs are fission bombs that do not involve fusion. In a fission bomb, the nuclei of uranium atoms are split, converting some of their mass to energy.All current fusion bombs include fission reactions to trigger the greater energy release from fusion. But most of the energy in very large fission-fusion bombs comes from a third-stage reaction: the fusion causes an exceptionally powerful fission reaction in a uranium shell around the bomb. This called a Teller-Ulam device or fission-fusion-fission bomb.


Why no fission on sun?

The core of the Sun is not dense or hot enough to sustain nuclear fission reactions like those in nuclear power plants. Instead, the Sun undergoes nuclear fusion, where lighter elements are combined to form heavier ones, releasing vast amounts of energy in the process. This fusion process sustains the Sun's energy output and keeps it shining.


Is fusion or fission the main energy source for stars?

Fusion is the main energy source for stars. It is the process by which stars convert hydrogen into helium through nuclear reactions, releasing a tremendous amount of energy in the process. Fission, on the other hand, involves the splitting of atomic nuclei and is not the primary energy source for stars.


Where in the Sun do fusion reactions happen?

core and radiation


Which is the cause of the sun energy?

Nuclear fission is the source of the sun's energy. It is a process in which an atom of hydrogen fuses with another atom of hydrogen, releasing large amounts of energy in the process. It is quite the opposite of nuclear fission, which is the source of atomic energy.

Which do you currently use nuclear fusion or fission?

I currently use nuclear fusion.


Can fission occur after fusion?

No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.

Which process, fission or fusion, releases more energy?

Fusion releases more energy than fission.


How does nuclear fission happen in the central of the sun?

The Sun gets its energy from fusion, not from fission. Ocassionaly an atom of a heavier element might go through fission, but that's hardly relevant for the working of the Sun.The Sun gets its energy from fusion, not from fission.

Is fission and fusion opposite?

Fission and fusion are opposite nuclear processes. Fission involves splitting a heavy nucleus into lighter ones, releasing energy, while fusion involves combining lighter nuclei to form a heavier nucleus, also releasing energy.


What is the difference in the processKEY WORD of fission and fusion?

in atomic science, fission is the splitting of atoms, fusion is the fusing of atoms
