10 paź 2012 · The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region. More detail on the outer layers follows: Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly.
3 lut 2024 · The four layers of the Sun are the core, radiative zone, convective zone, and atmosphere. The Sun is a colossal nuclear reactor at the heart of our solar system. Our favorite star is about 109 times the diameter of Earth and over 330,000 times its mass.
2 lut 2023 · Layers of the Sun. 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.
11 kwi 2022 · Something similar happens in the Sun. Its outer atmosphere is transparent, allowing us to look a short distance through it. But when we try to look through the atmosphere deeper into the Sun, our view is blocked. The photosphere is the layer where the Sun becomes opaque and marks the boundary past which we cannot see (Figure \(\PageIndex{4}\)).
The Sun, like other stars, is a huge spherical object made of hydrogen and helium. Its diameter reaches 1.400.000 km, or 109 times the Earth’s diameter; but is 4 times less dense than the Earth due to its composition. The Sun is not only made of the glowing gas that we see with a telescope.
26 wrz 2023 · A Transition Region – a thin and very irregular layer of the Sun’s atmosphere that separates the hot corona from the much cooler chromosphere. The Corona – the Sun’s outer atmosphere. Beyond the corona is the solar wind, which is actually an outward flow of coronal gas.
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.
