Cydonia is the name of a region on Mars has already attracted attention and interest for a long time scientists of astronomy enthusiasts and followers conspiracy theory. The region covers an area characterized by the phenomenon albedo (distinguished from neighboring areas with bright contrast), visible from Earth with a telescope, and includes Acidalia Planitia lowlands and Arabia Terra, and famous human face carved in relief Martian. The name comes from Kydonia Cydonia region, an ancient city on the island of Crete, in the place which today is the city of Chania. This region is positioned in the northern hemisphere of the planet, in the transition zone between cratered southern and northern areas dominated by plains and smooth. Some theories say that northern areas had been flat in the past oceans and Cydonia, a coastline. The most spectacular landform Cydonia region is the human face. Long time, has sparked controversy and attracted people's attention because the strikingly resemble a human face. Human face of Martian topography population was first shown in 1976. Picture was of interest to astronomy enthusiasts and conspiracy theories that have tried to find a possible explanation for the mysterious formation. Also, the human face spawned a series of science fiction literary creation who say this odd structure has natural origins, but should be done artificially by people or aliens. In 1976, a series of photographs of the surface of the planet were made by Viking 1 spacecraft, sent to Mars in NASA's exploration program. The mission lasted more tecdoc than six years, until 2010, he held the record for the longest Mars surface mission unfolded. The first pictures of the Cydonia region show a human face on the planet. Initially, the scientists responsible Viking project stipulated that the human face is, in fact, than an image created by the lights and shadows on the Martian surface. However, another set of pictures, even if they were made from a different angle, and they were surprised to humanoid. In reality, the mysterious figure is only a hilly formation on Martian surface More than 20 years capturing images of the Viking 1 spacecraft NASA sent to Mars further in other programs of surveying and exploration of the planet. Surface shuttles have carried pictures of the Cydonia region, this time in much better resolution than images from 1976. In the new photos, it was possible to create a three-dimensional image of the human face revealed that, in reality, the mysterious figure is only a hilly formations on the Martian surface. Likeness of a human face in special conditions does not occur until light and only from certain angles. Optical illusions like this can be seen on earth. In the U.S., the figure of an old man consists of rocks on Cannon Mountain, White Mountains (New Hampshire). Another example is the Pedra da Gavea, a monolith in Brazil, viewed from a certain position, giving the impression of a human face. Alien conspiracy enthusiasts and organizations whose point of interest were extraterrestrial civilizations have speculated that human figure on the Martian surface was made by a long vanished extraterrestrial population. The theory was supported by the so-called pyramids on Mars, evidence of that in the past, a Martian civilization have lived there and in their wake have left only the ruins of a city. Human image was taken from popular culture and used in movies, TV series, in literature, in music or comics. An excellent example of this is the song Knights of Cydonia of rock band Muse. An episode of The X-Files entitled Space describes the case of an astronaut during a space mission, was possessed by an alien spirit.
