Mysterious "fairy circles" spotted globally, origin still unknown
- Fairy circles are ring-like barren patches surrounded by vegetation, found in over 15 countries on 3 continents.
- First seen from space in 2021, scientists have studied fairy circles for decades but their cause remains a mystery.
- Leading hypotheses suggest fairy circles may be formed by self-organizing plants, termites, or toxic latex from succulents.
- All fairy circle sites share environmental similarities like aridity, temperature extremes, sandy soil low in nutrients.
- As of September 2023, researchers have yet to conclusively determine the mechanism behind fairy circle formation.
