Up to now, the existence of circles stretching across the Namib remains a mystery.
"Fairy circles" are circle gaps, distributing evenly on arid grasslands throughout Namib, a coastal desert in Africa. Seeing from above, they look like Polk dots on a piece of fabric.
They have the smallest diameter of about 1.5 m and are larger when going north. The biggest circles are found in the Angola territory with a diameter up to nearly 40m. A round can exist for at least 75 years.
By 2014, these circles only appear along the Namib but after that people find out this phenomenon near the mining town of Newman, north of Australia. Although, the fairy circles in Namibia are more famous and attractive for tourists.
There are many legends saying about the existence of the circles. Local people nearby belive that these are footprints of deities or a dancing space of fairies. Others believe that these are landing off places of UFO at night.
The popularity of the circles has also attracted scientists since the 1970s. They put out many theories about the formation and purpose of the circles. One of these was relating to termite colonies. Some scientists believe that termites chosen Namib as home. They nest in the soil, underneath the dry grassland. This theory believes that colonies of termite always seek ways to kill each other. When they encounter colonies of similar size, and cannot destroy each other, they create buffer zones - places where there are no termites - to separate the nests. And those are the circles. However, one study conducted on the newer circle in Australia showed termites are not the cause.
Another theory said this is a result of the competition of vegetation for scarce water every year in the desert. But until now, no one can show evidence and correct answers, therefore the fairy circles remain a mystery that lasts nearly half a century.
Plus: Namib means "big place". Indeed, this desert extends over 2,000 km along the Atlantic coast of Angola, Namibia, and the Republic of South Africa.
There are three ways to best admire these circles. You can see it directly from the ground, from a hot air balloon or from a small plane.
