Explore the Sun's core, the site of nuclear fusion where hydrogen converts into helium, powering the Sun. Surrounding the core, the radiative and convective zones facilitate energy transfer, while the photosphere emits visible light. The extended atmosphere, from the chromosphere to the heliosphere, plays a crucial role in solar dynamics and influences the solar system.

The core of the Sun is where nuclear fusion occurs, converting hydrogen into helium and generating immense amounts of energy
The primary mechanism of fusion in the solar core is the proton-proton chain reaction, responsible for most of the Sun's luminosity
In more massive stars, the CNO cycle also contributes to energy production in the solar core
Energy is transported outward from the solar core through the radiative zone primarily through the process of radiation
The convective zone, located above the radiative zone, is characterized by convective currents that transport energy to the surface of the Sun
The tachocline, a shear layer between the radiative and convective zones, plays a crucial role in the solar dynamo process that generates the Sun's magnetic field
The photosphere is the visible layer of the Sun's atmosphere, where most of the Sun's radiation escapes into space
The chromosphere, located above the photosphere, is a layer of lower density and higher temperature, visible during solar eclipses as a reddish glow
The corona, the outermost layer of the Sun's atmosphere, is surprisingly hot and extends far into space, giving rise to the solar wind
The Sun radiates energy across the electromagnetic spectrum, with sunlight providing vital energy for life on Earth
Neutrinos, elusive particles generated during nuclear fusion in the solar core, provide a direct probe into the Sun's fusion processes
