The Fairy Circles are millions of circular honeycomb-like patches across the Namib Desert in Southern Africa.
These disks of bare soil, known as fairy circles, look as if giant moths have chomped through the vast carpets of grassland.
There are lots of theories as to what causes the patches.
Some scientists have suggested radioactive soil, or that certain toxins released from plants kill the vegetation around them in circular patterns.
Others believe the circles are the work of sand termites.
