Deep within the core, where temperatures exceed 15 million degrees Celsius and pressure is immense, hydrogen nuclei collide with such force that they overcome their natural repulsion. Beyond that is the convective zone, where hot plasma rises, cools, and sinks in a pattern similar to boiling water.
Understanding Sunspots and the Sun's Magnetic Activity Cycle
The Layers: From Core to Corona The sun is not a uniform blob of gas; it is structured in distinct layers, each with unique properties and functions. This celestial body is not a solid surface but a churning mass held together by its own gravity and powered by nuclear fusion at its core.
Above this lies the chromosphere and the outermost layer, the corona, a region of superheated plasma that extends millions of kilometers into space and is visible only during a total solar eclipse. While it appears as a fiery yellow disk, the sun is primarily composed of the simplest elements in the universe.

The next most abundant component is helium, making up about 24% of its mass, a byproduct of the very reactions that power the star. This outflow creates a vast bubble around our solar system known as the heliosphere, which acts as a protective shield against a significant portion of the high-energy cosmic rays coming from other parts of the galaxy.
