The origins of eerily perfect circles in the eastern Namib desert have puzzled scientists for decades. The circles, seen as patches of bare soil on otherwise arid and grassy terrain, appear equidistant to one another, as if someone methodically took a cookie cutter to the ground.
Satellite imagery shows there could be millions of these “fairy circles” in the area, but scientists have debated what could explain the existence of even one, which can span up to 20m in diameter. Perhaps termites are chomping at the plant roots? Maybe the grasses are somehow creating the patterns? Or a toxin has decimated the soil? Or maybe aliens are sizing up the desert as a potential landing spot (spoiler: it’s never aliens)?
