• 6 amazing things created by man that can be seen from space
The Earth is large, and in a few millennia, people have filled it with a great and wonderful things: the pyramids, the gigantic walls, and many other metropolitan areas. But for the International Space Station (ISS), which orbits the Earth at an altitude of 400 km, our planet may seem pretty small place. Houses, roads and buildings just disappear. Even some of the greatest man-made structures merge with the landscape. But there are those that can be seen from the height of Earth orbit.
The Great Pyramids of Giza
See small triangular shadows in the center of this image? These shadows and small specks beneath them - some of the most amazing structures ever erected by man. These are the three most famous ancient Egyptian pyramids - the pyramids of Giza. The biggest of the three - more than 140 meters in height, but from outer space it looks like a small dot in the middle of the desert.
Night city lights

Copper Mine Kennecott
Kennecott Copper Mine to the south-west of Salt Lake City - one of the largest open pit mines in the world. Its diameter is about four kilometers, and depth - more than 1200 meters. Even at the end of XIX century there was mined gold, silver and lead.
Humanity builds bridges for a long time and every year - all the better.

Such bridges can withstand a load of millions of cars a year. In the photo - the Golden Gate Bridge in San Francisco.
Palm Islands in Dubai
Dubai extends along the coast of a man-made archipelago of islands in the form of palm trees. To build these islands, the builders were getting sand from the bottom of the Persian Gulf, and then shaped it into the palm trees and other shapes. The island at the top of this picture is still under construction. It is designed in the form of a world map.
