What Is the Sun Made Of? The energy, mostly in the form of gamma-ray photons and neutrinos, is carried into the radiative zone. Photons can bounce around in this zone for about a million years before passing through the interface layer, or tachocline. Scientists think the sun's magnetic field is generated by a magnetic dynamo in this layer.

The Sun's Radiative Zone In the convective zone, heat and energy are carried outward along with matter in swirling flows called convection cells. This motion is similar to the roiling flows seen in a pot of boiling water. The inner parts of the Sun (core and radiative zone) spin differently than the outer layers (convective zone).n the convective zone, heat and energy are carried outward along with matter in swirling flows called convection cells.

- Thermonuclear fusion is the process in which a star produce its light, heat, and energy. This happens at the core of the star. The core is superheated to millions of degrees. This heat travels towards the surface and radiates out into the universe.

How does the Sun shine? The Sun shines by turning hydrogen into helium in its core. This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.The famous scientist Albert Einstein discovered a formula which shows how much energy can be created from a small amount of mass.his can only happen in places which have extremely high pressures and temperatures. At the center of the Sun, the temperature reaches 16 million degrees K, and the pressure is more than a billion times the atmospheric pressure on Earth! The Sun converts about 5 million tons of mass into energy every second.

- Inner Core. The Inner Core of the Sun is the main engine of this star. Here, gravity and heat provide the necessary energy to drive the nuclear fusion processes that power the sun. In the core, the fusion processes called the Proton-Proton Cycle and the Carbon-Nitrogen-Oxygen Cycle take place.

- The convection zone is the outermost layer of the sun's interior. It extends from about 125,000 miles (200,000 km) deep up to the visible surface or the sun's atmosphere.Temperatures cool in this zone, enough for heavier ions — such as carbon, nitrogen, oxygen, calcium and iron — to hold onto their electrons.hese elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The temperature of the sun in this layer is about 27 million degrees F (15 million degrees C).

- Producing Energy (Fusion) The sun produces heat, light, and radiation through the process of fusion. Fusion occurs when a substance is so hot that atoms gain and lose particles, actually changing from one type of element to another.

Where in the Sun Does Nuclear Fusion Occur? In the sun's core, hydrogen is converted into helium during nuclear fusion. Once this process is complete, the energy from the core makes its way to the surface, where it cools down to around 10,000 F. Because of the ongoing nuclear fusion going on in the center of the sun, the sun neither grows nor collapses under its own weight.

The Sun Deep in the sun's core, nuclear fusion reactions convert hydrogen to helium, which generates energy. Particles of light called photons carry this energy through the sun's spherical shell, called the radiative zone, to the top layer of the solar interior, the convection zone.he sun's surface, or atmosphere, is divided into three regions: the photosphere, the chromosphere, and the solar corona. The photosphere is the visible surface of the sun and the lowest layer of the atmosphere.

- When the temperature in the core reaches about 100 million degrees, the helium will begin to fuse into carbon by a reaction known as the triple-alpha process, because it converts three helium nuclei into one carbon atom.This generates a great deal of heat.n heavier stars, the oxygen can in turn fuse with the helium to make neon.) Helium fusion produces only 9% as much energy per kilogram as hydrogen fusion, so energy-wise, the Sun continues to be mainly a hydrogen reactor. 90% of its luminosity still comes from burning hydrogen.

- Nuclear Reactions in Stars. The energy of the stars comes from nuclear fusion processes. For stars like the sun which have internal temperatures less than fifteen million Kelvin, the dominant fusion process is proton-proton fusion. For more massive stars which can achieve higher temperatures, the carbon cycle fusion becomes the dominant mechanism.

The Electromagnetic Spectrum The Sun is a star-a furnace in which hydrogen nuclei undergo fusion to produce helium (and much rarer and heavier elements), and during which, about 0.3% of their mass is converted to energy.

- Our Sun was born within a dense nebula 4.6 billion years ago. Gas and dust contracted into a giant cloud, then floated in one of the spiral arms of the Milky Way. As our Sun aged, it grew larger, brighter, and hotter — eventually causing nuclear fusion in the protons at the centers of its atoms.

- The sun generates energy from a process called nuclear fusion .During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released. It can take 150,000 years for energy in the sun’s core to make its way to the solar surface, and then just a little over eight minutes to travel the 93 million miles to Earth.

Nuclear Fusion Fusion is the process by which the sun and other stars generate light and heat. It is a nuclear process, where energy is produced by smashing together light atoms. It is the opposite reaction to fission, where heavy isotopes are split apart. It’s most easily achieved on Earth by combining two isotopes of hydrogen: deuterium and tritium.

What is Plasma? Numerous collisions in the core of the sun freed electrons from ions, forming a plasma state. Fusion began in the sun when collisions between ions became so frequent that the ions got close enough to fuse together. The sun uses gravity to get its nuclei close enough and hot enough to start fusion.
