The Earth appears exceptionally clear, with no clouds obscuring it, and you can see the boundaries of land, sea, and atmosphere. Earth's blue atmosphere surrounds the planet, giving a striking contrast, making the Earth look like a brilliant sapphire against a dark cosmic background.
Earth's surface features are clearly visible, such as the outline of continents, white cloud bands, and even large-scale deserts and forests. When sunlight hits different parts of the Earth, you can see the changes in light and shade on the Earth, just like observing the phases of the Moon on Earth, but in opposite directions. During the day, parts of the planet shimmer with sunlight, while at night, city lights converge into a star-like pattern, especially in densely populated areas.
Since the Moon's rotation and revolution period are synchronized with the Earth, the Earth is always fixed in a relative position, giving a sense of stability and long-lasting presence. People who live on the moon may often face the same "starry sky", only the light and shadow of the earth remind of the passage of time. Such a sight may provoke deep reflections about the insignificance of human beings, the importance of home, and the endless mysteries of the universe.
However, this constant gaze can also have a psychological impact. There is no alternation of sunrises and sunsets, no changes in the weather, and the earth always serves as a huge reference point, which can give rise to complex emotions that are both familiar and strange. This feeling may be both awe and a certain loneliness and awe, after all, it is the only place where we know that life exists.
