Round discs of barren dirt known as “fairy circles” look like rows of polka dots that can spread for miles over the ground. The phenomenon’s mysterious origins have intrigued scientists for decades — and they may be far more widespread than once thought.
Fairy circles were previously spotted only in the arid lands of Southern Africa’s Namib Desert and the outback of Western Australia. But a new study has used artificial intelligence to identify vegetation patterns resembling fairy circles in hundreds of new locations across 15 countries on three continents. This could help scientists understand fairy circles and their formation on a global scale.
