The Sun, our closest star, is an inexhaustible source of mysteries and intriguing phenomena. Although we see it as a bright sphere in the sky, the Sun is actually a complex and dynamic object with a number of structures and parts that play a vital role in our understanding of the universe.

Solar Nucleus: The Burning Heart

The solar core is the center of the star and where the nuclear reactions that power the Sun occur. In its core, hydrogen fuses into helium at extreme temperatures and pressures, releasing enormous amounts of energy in the form of light and heat. These nuclear reactions keep the Sun shining constantly and provide the energy that sustains life on Earth.

The Radiant Zone: A Sea of ​​Photons

From the core, energy travels to the Sun’s surface through an area known as the radiant zone. Here, energy spreads in the form of photons, particles of light that continually bounce around a labyrinth of charged particles. This process can take thousands of years due to the density of the material in this region.

Photosphere: The Visible Surface

The photosphere is the visible surface layer of the Sun, where most of the sunlight that reaches Earth is produced. This layer is known for its distinctive features, such as sunspots and granulations, which reveal dynamic activity on the solar surface.

Chromosphere: A Glow in Red

The chromosphere is a layer of hot, tenuous gas that surrounds the photosphere. During a solar eclipse, the chromosphere becomes visible as a bright red ring around the Sun. Here, interesting phenomena such as solar prominences, which are jets of hot gas rising from the surface, can be observed.

Crown: The Fiery Crown

The solar corona is the outer atmosphere of the Sun, and is much hotter than the surface of the Sun. This layer emits visible light during a total solar eclipse and is the source of the solar wind, a stream of charged particles that constantly flows from the Sun. into interplanetary space.
