Mysterious "Fairy Circles" in Namibia
Why are these Foreign Circles?
In the desert of Namibia are drawn some foreign circles, surrounded by a ring of high vegetation, and in the interior not grows the grass. How you form these circles? The mystery has caused fascination for decades scientists and curious. Known as the "circles of fairies", these strange formations in Namibia, have captured the attention and this give the foot to some interesting theories. This show us that there are many unknown curious things that happen in our strange planet.

How the "foreign circles" of Namibia are formed?
Theories
These circular formations have different sizes, some measuring a few metres in diameter, while others have come to measure 20 meters. South African Researchers , for example, they believe that the circles are formed by the toxic action of the plant Euphorbia gummifera, but there are other popular theories. Some suggest natural gas filtration to emanate from the depths creating this phenomenon.
Another researcher, Norbert Jürgens, has published their conclusion in 2013 in the Journal Science: termites of sand are responsible for the creation of these circles. The termites eat the ephemeral vegetation that appears after the rain, leaving circular sterile spots. Due the rapid infiltration and lack of evapotranspiration, water is retained within the circles. This process results in the formation of rings of vegetation that facilitate the survival of termites, Especially by the prolonged drought.

Another theory is the self-organization, known as theory of the formation of natural patterns, raised by the British mathematician Alan Turing in 1952, which explains how patterns and structures emerge in natural systems, from an embryo up to the stripes of a zebra. In fact, Japanese researchers discovered that the circles in the desert of namibia shared pattern with cells of the skin.
How is this theory applied to Namibia fairy circles? In a few words, the nature is organized to take advantage of the water. "To organize in circles, the vegetation of they surroundings benefits of a additional source of water, because the rain in the clearing of lands find his road, through several mechanisms of transport of water", says Stephan Getzin, that studied the fairy circles in Australia. In Australia the water flows over the surface, while in Namibia, according to those who hold this theory, the stored water flows through the roots of vegetation.
What is the true explanation?
Remains in mystery, now that the researchers are not agree, for example, in Australia ensures that there are no termites, and meanwhile Jürgens ensures that if the self-organization were true, this phenomenon would occur all over the world. In addition soil of Namibia and Australia are different, while in Namibia water infiltrates, in Australia clay water repellent, running on the surface.
Surely we will continue intrigued by the mysterious formation of circles. At the end of accounts are of those curious things that the science does not can explain yet.
