Scientists have solved the long-standing mystery of Antarctica’s Blood Falls, a striking red waterfall that flows from the Taylor Glacier. The phenomenon, first discovered in 1911, was long thought to be caused by red algae. However, new research reveals the true source: the water originates from a subglacial reservoir rich in iron. When this iron-rich water emerges and contacts oxygen, it oxidizes, creating the vivid red color that resembles blood. The study also confirms the water flows through fissures in the glacier, not from melting ice, and is part of a unique and ancient hydrological system isolated for potentially millions of years. This discovery provides insights into extreme life forms and hydrological processes in Antarctica.
