Get this: scientists just found a whole new way oxygen is made nearly 4,000 meters below the Pacific—no sunlight needed! Turns out, metal-rich rocks on the seafloor act like natural batteries, splitting water and pumping out O2 in total darkness. This 'dark oxygen' discovery is shaking up what we thought we knew about ocean life, and could even change how we look for life on other planets. Mining these rocks? Now a way bigger deal than anyone thought! #Science #DarkOxygen #DeepSea
