10 paź 2012 · Corona – The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K.

3 lut 2024 · Solar Atmosphere. The solar atmosphere is the outermost region of the Sun, visible during total solar eclipses. It consists of three primary layers: Photosphere. Thickness/Size: Approximately 500 kilometers. Temperature: Around 5,500°C. Characteristics: The photosphere is the Sun’s visible surface, where light is emitted that we see from Earth.
The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. There are four outer layers of the Sun, and the Corona is the outermost one.
2 lut 2023 · The sun has seven different layers, which are further divided into three inner and four outer layers. The names of these layers, in order of their presence from the core of the sun are as follows: Inner Layers. 1) Core. 2) Radiative Zone. 3) Convection Zone. Outer Layers. 1) Photosphere. 2) Chromosphere. 3) Transition Region. 4) Corona
The Sun’s outer gases extend far beyond the photosphere (Figure 15.7). Because they are transparent to most visible radiation and emit only a small amount of light, these outer layers are difficult to observe. The region of the Sun’s atmosphere that lies immediately above the photosphere is called the chromosphere.
Moving outward, in the convection zone, the temperature drops below 3.5 million °F (2 million °C). Here, large bubbles of hot plasma (a soup of ionized atoms) move upward toward the photosphere, which is the layer we think of as the Sun's surface.
The Sun viewed at different wavelengths of light reveals its outer layers. White is visible light from the photosphere. Red is ultraviolet light from the chromosphere. Blue and green are extreme ultraviolet light from the corona.
