From the surface of the sun the heat radiations take 8 minutes to reach the surface of hte earth.
The article linked below discusses this and is an interesting read
yes nuclear fusion does occur on the sun, creating intense heat and light
Starting the fusion reactions required high density and high heat.
With the exception of vanishingly small amounts from other stars, heat does not reach the sun. The sun is a source of heat due to the nuclear fusion underway in its interior.
More reach the surface of the moon because there is no atmosphere to heat and burn them up.
Nuclear fission and reaction, intense heat.
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
It attempts to reach the surface of the Earth.
Definitely. Nuclear fusion is the source of all the light, heat, and other energy generated and radiated by every star you see, including the sun.
Scientists are having difficulty converting the heat into electricity.
sun, fire ,and stove are all examples of heat energy!For example heat released during chemical reactions, nuclear fission, nuclear fusion, etc.
In the center. Heat then flows out to the outer surface by radiation and convection
