The Cool News: "The Great Wall of China is NOT particularly visible from space While at a low orbit, the Great Wall of China can certainly be seen from space but it is not unique in that regard. From a low orbit of the earth, many artificial objects are visible on the earth, not just the Great Wall of China. Highways, ships in the sea, dams, railroads, cities, fields of crops, and even some individual buildings. As to the claim that it%u2019s the only man-made object visible from the moon, Apollo astronauts have reported that they could not see any man-made object from the moon, not even the Great Wall."

Read the comments. Really geeky stuff.
