How does energy produced by nuclear fusion move from sun's core to space?

As 4 hydrogen atoms fuse to make the 1helium energy is release in the process. The Atomic Mass of hydrogen is 1.00794 and it takes 4 of them. The atomic mass of helium is 4.002602.
4 * 1.00974 (hydrogen atomic mass) = 4.03176
But helium's atomic mass is less than that at 4.002602
There is a missing 0.029158 worth of mass that didn't become helium.
The missing mass is converted into energy when the 4 hydrogen's are created by the equation E=mc2. The core is so tightly compressed that this energy "bounces" around being reabsorbed and re-emitted for about 100,000 years, yes I know that sounds made up but this is what I learned in Astronomy. Once it reaches the surface of the sun it is released as the Electromagnetic Spectrum which is Gamma, X-ray, ultraviolet, visible, infrared, microwave radiations, and radio waves.
In stars much larger than our sun all the elements up to Iron are formed. Anything heavier than Iron it is theorized are made in supernova.

What is the oppoiste of fission?
I am not sure if there is an opposite of fission, where an atom is split in half, but if there was an opposite it would probably be nuclear fusion, where two nuclei join together giving off energy. Nuclear fusion occurs in space, and it is how the sun gives off its energy.
How its nuclear energy produce and how its distributed?
it depends, where. The sun or the factory. The facories uses nuclear fission. This means they split atoms, usually uranium. Then it heats up quickly. The factory must use water to cool it down. The steam turns turbines to make energy. If they are not enough water, then there will be a melt down. In the sun. It uses nuclear fusion. This means it combines atoms together. this happens in the core. then energy is radiated to the convection zone, then the energy reaches the surface and radiates its energy in to space.
What energy type is generated by nuclear energy?
Nuclear decay produces energy that can be regarded either as kinetic energy or as heat. It is measured in electron volts. If that is confusing, the confusion arises from the fact that we are operating at the atomic level, which most people never have the opportunity to observe. Heat is actually the amount of energy in atoms as they move about in space. It is related to the speed of the atoms, which is kinetic energy. We do not get a sense of this because at our level, the atoms are not observable, and since their motion is random, and there is an immense number of them, they cannot move objects in any way we can observe visually or by feel. We observe is the excitation as heat. An electron volt is not a unit of electricity, but a unit of kinetic energy. It is the amount of energy gained by an electron accelerated through an electric potential difference of one volt. It is the difference of energy caused by a difference in speed.
How could nuclear energy make long space trips more practical?
Nuclear energy could provide power for long periods, and the energy necessary for advanced high-speed propulsion in space. However, chemical rockets would still be needed to reach Earth orbit, because nuclear engines are space drives: they do not have the lift-to-weight ratio needed to achieve escape velocity. (This was once proposed as a use for nuclear bombs, but the launch system would create massive radioactive pollution.)
Which energy source is used in nuclear power plants?
Uranium or Plutonium, but any fissionable material can be used. These radioactive materials will fission when struck by a neutron; releasing energy, radioactive fission products, and more neutrons (which continue the chain reaction).
What produces most of the sun's energy?
Most of the energy of the sun is produced by nuclear fission. The heat at the core convects to surface and is radiated outward into space. The earth is the fortunate recipient of that process.
Can nuclear energy be used everywhere?
Yes. There are virtually no physical limitations to where nuclear power can be used. Nuclear reactors have already been used on land, air and sea... and submerged and in space. Not only we humans use nuclear energy, but it is the primary source of energy in natural processess in the world too. Life on earth depends on the sun's energy, which in part is produced by nuclear fusion in the heart of the star.
How do star use energy?
Stars fuse hydrogen through nuclear fusion into helium and release the massive resulting energy into space.
Is it true that chemical reactions produce the energy that the sun radiates out into space?
Yes this is true it is called nuclear fusion.
How does the sun radiate energy?
The sun radiates energy through nuclear fusion. This causes helium atoms to be formed which then become excess energy that moves into space.

Is The process that produces the energy in the cores of most stars nuclear fission?
No, it is nuclear fusion. Fission is the splitting of heavy atoms, such as uranium. Fusion is the combining of light atoms into heavier atoms.Stars get their energy from fusion, combining hydrogen into helium, and eventually, helium into metals. (In Astronomy, a metal is any element heavier than helium.)This is both the source of energy for stars, and the explanations why we have metals (oxygen, carbon, etc.) on Earth. The heavy elements were produced in stars; some of them went to space and participated in the formation of new solar systems.
What is an example of nuclear fission which is applicable in your daily life?
We are constantly bombarded by cosmic radiation from space, and background radiation from the soil. However, both are background, and we have no biological processes that depend on nuclear reactions to survive.
What layer of the sun's interior is where energy is released to maintain its high surface temperature while the sun radiates energy into space?
The Layer of the sun's interior where energy is transderred mainly my electromagnetic radiation is cheese and llamas. Just kidding. It is nuclear fusion. -katie k bye
How do stars like the sun create energy that is later radiated into space?
The energy comes from "nuclear fusion". Stars like the Sun create helium from hydrogen by this method, and that gives out energy. That's how the Sun creates energy.
Energy produce by or coming from the sun?
** nuclear fusion of hydrogenNuclear EnergyHydrogen atoms fuse to give Helium.The energy released is in the form of electromagnetic radiations,which travel through space and reach earth.These radiations are the primary source of all forms of energyand also it can be produced by the sun by solar panels
How do stars like the sun create energy that is later radiated away into space?
The energy comes from "nuclear fusion". Stars like the Sun create helium from hydrogen by this method, and that gives out energy. That's how the Sun creates energy.
