The brain is wide open, is the WeChat startup map taken on the moon?

A lonely little man, standing there facing the huge earth, is the launching screen of WeChat that many people are very familiar with. But do you know its secret? This is not a map, but a photo called "Blue Marbles". This photo was taken on1972 65438+February 7, when the astronauts were on the Apollo 17 spacecraft. One of the three astronauts took a complete picture of the earth with an 80 mm Hasselblad camera.

From the astronaut's point of view, from 45 thousand kilometers away, the earth looks like a tiny blue marble, which is the origin of the name of this photo.

Wechat's launch screen uses this "blue marble", which is a scene of human beings overlooking their home planet in space recently. As a tool of interpersonal communication, no second picture can better express the loneliness of human heart and the beauty of the earth's home. Therefore, the whole picture has a faint warmth in loneliness, giving people a feeling of literary withering. When you know the story behind it, you will feel that the talent show is dying.
