nation world news The sun became a giant star, the center of the solar system. The sun occupies 99% of the solar system, and the rest of the solar system is a collection of planets, vacuums, and various objects.
The age of the sun is estimated to be 4.603 billion years. The sun is the largest celestial body. The sun is a star because the light it produces is also good for Earth.
The source of solar energy comes from fusion reactions that take place in the center of the sun. This fusion reaction combines hydrogen atoms into helium.
Fusion reactions generate enormous amounts of energy. The Sun is made up of various gases, including hydrogen (76%), helium (22%), oxygen and other gases (2%).

Diagram of the order of the layers of the sun from innermost to outermost
The sun is a very hot ball of fiery gas. The sun consists of four layers as follows:
The interior of the sun, the core of the sun. Fusion reactions take place in this part as a source of solar energy. The temperature of the Sun’s core can reach 15,000,000 °C.
The energy from the fusion reaction will travel to the outermost layers and then be felt in outer space.
The photosphere is the surface of the sun. This layer emits light and can therefore provide everyday lighting. The temperature of this layer can reach about 16,000°C and the thickness is about 500 kilometers.
The chromosphere is the layer above the photosphere that acts as the sun’s atmosphere. The thickness of the chromosphere is 16,000 km and the temperature reaches about 9,800 °C.
During a total solar eclipse, the chromosphere looks like a red ring around the moon.

The corona is the outer layer of the sun’s atmosphere. The temperature of the corona can reach about 1,000,000 degrees Celsius. Due to its high temperature, the result of atomic ionization is gray.
The corona can be seen during a total solar eclipse because almost all of the sun’s light is covered by the moon at that time. Crown-shaped, like a brown crown.
interference with the sun
Being active in the sun or showing signs of solar activity often disturbs the sun. These diseases, namely:
These droplets are created by the diffusion of hot gas from the center of the Sun to the surface. As a result, the sun’s surface is not flat but uneven.
Sunspots are regions where very strong magnetic fields occur. These blobs are shaped holes in the sun’s surface where hot gas escapes from the center of the sun and can therefore interfere with radio wave communications on the Earth’s surface.

Solar glare is the scattering of gas from the edge of the sun’s chromosphere. The flames can reach heights of 10,000 kilometers.tongues of fire are often called chief anyone range,
The flame is made up of large numbers of protons and electrons produced by fast-moving hydrogen atoms. The mass of these particles can reach the Earth’s surface.
The emission of these particles before entering Earth is blocked by the Earth’s magnetic field (Van Allen belts), which slows the motion of these particles toward the poles, and then gradually glows. This is called an aurora.
Scattering of such particles can interfere with radio wave communication systems. In the Southern Hemisphere, the aurora is called the Southern Lights, while in the Northern Hemisphere it is called the Northern Lights.
A flame is an explosion of gas above the sun’s surface. Flares can interfere with radio communication systems because gas explosions consist of charged gas particles.
