The image is a photograph of a sign that explains the structure of the sun. The sign is rectangular in shape and has a black background with white text. On the left side of the sign, there is a white circle with a purple dot in the center. The text is written in both Chinese and English. Below the circle, there are two lines of text that explain the different types of suns and their properties.

The first line of text explains that the sun can be divided into core-nuclear reactions occur through radiation, convection zone-heat is transferred through convection, and the sun's atmosphere is divided into layers. The second line explains how the Sun's atmosphere can be affected by the sun and how it can be seen during solar eclipses. The third line explains that it can only be seen through the sun, but it can also be seen as a layer of sunlight. The fourth line explains the sun as a sun, which is a type of sun that is responsible for the formation of solar energy.
