Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
In the core of a star, high-energy gamma rays are produced through nuclear fusion processes. These gamma rays travel through the layers of the star, losing energy through interactions until they reach the surface. At the surface, the gamma rays are converted into visible light through processes like thermal radiation or scattering, making the star shine with visible light.

The layer of the sun's interior where energy is released to maintain its high surface temperature is the core. In the core, nuclear fusion reactions convert hydrogen into helium, releasing energy in the form of photons (light and heat) that eventually reach the sun's surface and are radiated into space.
The surface of the sun is hotter than the core of the Earth. The surface of the sun can reach temperatures of about 5,500 degrees Celsius, while the core of the Earth has temperatures reaching up to 6,000 degrees Celsius.
Energy generated in the sun's core through nuclear fusion can take up to a million years to travel to the surface and be released as sunlight. Once released, it takes about 8 minutes for the sunlight to travel the 93 million miles to reach Earth.
From the core, photons take about a million years to reach the surface. From there, they are free to travel and only take just over 8 minutes to reach the Earth.
Energy produced in the core of the Sun through nuclear fusion primarily in the form of gamma rays slowly travels outward through the radiative zone, where it is absorbed and re-emitted by particles, a process that can take thousands to millions of years. Once it reaches the convective zone, energy is transported more rapidly by convection currents, where hot plasma rises to the surface, cools, and then sinks back down. This combined process eventually allows the energy to reach the Sun's surface and be emitted as sunlight into space.
Energy in the form of light and heat is produced in the sun's core through nuclear fusion reactions. This energy then moves outwards through the radiative zone and convective zone before reaching the sun's surface (photosphere) and being emitted as sunlight.
The energy in the Sun is primarily produced in the core, where nuclear fusion reactions convert hydrogen into helium, releasing vast amounts of energy in the process. This energy then travels outward through the Sun's layers before being emitted as sunlight into space.
The Core
In the core
The Sun's structure consists of a core where nuclear fusion occurs, releasing energy in the form of light and heat. This energy gradually moves outward from the core through radiation and convection processes. The energy produced in the core is transferred to the Sun's surface, where it is emitted as sunlight.
It attempts to reach the surface of the Earth.
In the core of a star, high-energy gamma rays are produced through nuclear fusion processes. These gamma rays travel through the layers of the star, losing energy through interactions until they reach the surface. At the surface, the gamma rays are converted into visible light through processes like thermal radiation or scattering, making the star shine with visible light.
the core
The heat generated in the core of the sun is transported to the surface through a process called radiative and convective heat transfer. Energy in the form of photons moves outward through the radiative zone, and in the convective zone, hot plasma rises to the surface carrying heat with it.
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.
