What Is the Chromosphere?

Chromosphere: A layer of the star's atmosphere, surrounded by a photosphere. Usually, because the molecules and dust particles in the earth's atmosphere scatter strong solar radiation and form a "blue sky", the chromosphere and the corona are completely submerged in the blue sky.

The average thickness of the spheroid layer is 2000 kilometers. The density is thinner than the photosphere layer. Temperatures range from several thousand to tens of thousands of degrees Celsius; but the light emitted is only a few thousandths of the photosphere layer.

Usually, the chromosphere layer cannot be seen. Only when a total solar eclipse occurs, a curved red light can be seen on the edge of the dark sun wheel for only a few seconds. This is the brilliance of the chromosphere.

The temperature at the top of the photosphere is 4300 degrees Celsius, while the temperature at the top of the color globe is tens of thousands of degrees. The exact cause of this anomaly has not yet been identified.

The most prominent feature on the colored ball is the needle. They appeared on the edge of the sun wheel, like small tongues of fire, occasionally emitting bunches of fire. It only takes about 10 minutes for the needles to disappear.
