What layer of the sun is it that we usually see?

The outer structure of the Sun The Sun that we can directly observe is the Sun's atmosphere. It is divided into three layers, the photosphere, the chromosphere, and the corona, from the inside to the outside

Photosphere. The surface of the sun, which we see as bright and glowing like a disk, is called a "photosphere". It is a very thin layer on the outer part of the sun, only about 500 kilometers thick, with a surface temperature of about 6000 k.

Sunlight is basically emitted from this layer. There are some dark spots on the surface of the photosphere, called solar "sunspots".

Chromosphere. Outside the photosphere, there is a rose-colored solar atmosphere. This layer is called the chromosphere.

It is about several thousand kilometers thick, the gas is thin, and the visible light emitted is less than one-thousandth of the photosphere. Therefore, it is only visible to people during a total solar eclipse (or with a special telescope). The temperature of the chromosphere is determined from the inside out.

Four or five thousand degrees rises to tens of thousands of degrees. In the chromosphere, red flames of tens of thousands to hundreds of thousands of kilometers are sometimes violently spewed outward, which is called the sun. Some areas of the chromosphere have a sudden brightening in a short period of time.

This phenomenon is called flare, also known as solar chromosphere explosion.

Coronal layer. The chromosphere is also surrounded by a very thin, completely ionized layer of gas. This layer is called the corona.

It extends outward from the edge of the chromosphere to several solar radii and beyond. It is only one millionth brighter than a photosphere and can only be seen during a total solar eclipse or with a specially made coronagraph. The temperature inside the corona is as high as 1 million degrees, and the corona is farther away from the surface of the sun, which is less gravitational, and its high temperature causes the high-energy charged particles to move outward.

This stream of particles moves at a very high speed, reaching more than 350 kilometers per second, and constantly flies into interplanetary space, like a "wind" blowing from the sun, so it is called "solar wind".

Photosphere. Give me the flag!

The circle of the sun that we see is called the photosphere, which is about 500 kilometers thick, and the bright and dazzling sunlight emits from this layer.

The photosphere is in the lowest layer of the Sun's atmosphere. With a thickness of about 500 kilometers, the photosphere is so thin relative to the radius of the Sun that it is sometimes referred to as the surface of the Sun. The lower layer of the photosphere has a higher temperature of about 5800 K and the upper layer has a lower temperature of about 4400 K, from which all solar radiation is generated.

The photospheres are filled with rice grains, which are actually formed by the hot air masses rising in the troposphere hitting the surface of the sun. In the active area of the photosphere, there are sunspots, light spots, etc. ]

Because it is the brightest, it has obscured the light of the outer circle

The rest of the layers can only be seen during an annular solar eclipse

So it's the photosphere!

The atmosphere of the sun, like the atmosphere of the earth, can be divided into various layers according to different heights and different properties, that is, from the inside to the outside, it is divided into three layers: the photosphere, the chromosphere and the corona. The surface of the sun, which we usually see, is the lowest layer of the solar atmosphere, with a temperature of about 6,000.

The sun that is normally seen with the naked eye during the day is its photosphere. The photosphere is the lowest layer of the sun's atmosphere, that is, the surface of the sun observed by white light, with a thickness of about 500 kilometers, and the amount of solar energy we receive is basically emitted by the photosphere.

There is intense activity in the atmosphere of the photosphere, and you can see with a telescope that there are many dense spot-like structures on the surface of the photosphere, which resemble rice grains, which are called rice grain tissue. They are extremely unstable, last only 5-10 minutes, and their temperature is 300-400 degrees higher than the average temperature of a photosphere. At present, scientists believe that this rice grain tissue is caused by the violent convection of gas below the photosphere.

The sun seen by the naked eye during the day is a ball of light. The sun that can be directly observed is the sun's atmosphere. It is divided into three layers: the photosphere, the chromosphere, and the corona

1. Photosphere: The surface of the sun, which is bright and glowing like a disc, is called a "photosphere". It is a very thin layer on the outside of the nightshade sun, only about 500 kilometers thick, and the surface temperature is about 6000 k. Sunlight is basically emitted from this layer.

2. Color sphere: On the outside of the photosphere, there is a layer of rose-colored solar atmosphere. This layer of tremor is called the chromosphere layer.

Its thickness is about several thousand kilometers, the gas is thin, and the visible light emitted by hand is less than one-thousandth of the light sphere. Therefore, it can only be seen by people during a total solar eclipse (or with a special telescope).

3. Corona: A very thin, completely ionized gas layer is also surrounded by the chromosphere. This layer is called the corona.

It extends outward from the edge of the chromosphere to several solar radii and beyond. It is only one millionth the brightest of a photosphere and can only be seen during a total solar eclipse or with a specially made coronagraph. Therefore, what can be seen with the naked eye is the sun's photosphere.

d.Magnetic sphere layer.

The solar disk we usually see, bright and dazzling, is which layer of the solar atmosphere next to the sun? （）

Photosphere (correct answer).

Chromosphere. The corona layer carries the enlightenment.
