From the surface of the sun the heat radiations take 8 minutes to reach the surface of hte earth.

yes nuclear fusion does occur on the sun, creating intense heat and light
The Sun is the primary source of heat and light for all the planets in our solar system. It emits energy through nuclear fusion reactions in its core, which produces heat and light that reach all the planets, including Earth.
The heat of the sun comes from nuclear fusion reactions in its core. These reactions convert hydrogen into helium, releasing enormous amounts of energy in the form of heat and light.
The temperature of the core of a star can reach millions of degrees Kelvin due to nuclear fusion reactions that generate immense heat and light. This intense heat and pressure in the core are what sustain a star's energy output.
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.
Fusion occurs predominantly in the core of stars, where the extreme pressure and temperature create the conditions necessary for nuclear fusion reactions to take place. In this process, hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the form of light and heat.
Heat from the sun is generated by nuclear fusion reactions within its core. These reactions release energy in the form of electromagnetic radiation, including heat and light, which is then radiated outwards through space. Earth receives this heat in the form of sunlight.
Nuclear fission and reaction, intense heat.
The sun shines because of nuclear fusion reactions occurring in its core. These reactions release energy in the form of light and heat, which illuminates our solar system. The sun will continue to shine as long as it has fuel to sustain these fusion reactions.
It attempts to reach the surface of the Earth.
