Oxygen and life on Earth are inextricably linked. Oxygen is essential for sustaining life, and our atmosphere contains a significant amount (21%). Scientists previously believed that oxygen levels increased due to photosynthesis and cyanobacteria. However, recent discoveries in deep-sea environments have challenged this notion.

Researchers found "dark oxygen" in the Clarion-Clipperton Zone (CCZ) at 4,000 meters below the Pacific Ocean's surface. This oxygen is produced without sunlight or photosynthesis, through a chemical process involving polymetallic nodules. These nodules act like "geobatteries," generating a natural voltage that splits seawater into hydrogen and oxygen.

This discovery has significant implications for our understanding of aerobic life's origins and the potential environmental impacts of deep-sea mining. It also suggests that where water is found, oxygen may also be present, which could facilitate space exploration and colonization.

The findings highlight the complex relationship between water and oxygen in the universe, and further research could reveal more about the possibilities for life beyond Earth.
