Much of the water on Earth could have been produced from dry silicate pebbles falling through the hot, hydrogen-rich primordial atmosphere as the planet formed. High-temperature experiments in streams of pure hydrogen demonstrate that the reduction of iron oxide in the silicates can produce water vapour in minutes or hours, and suggest that water production on Earth-sized exoplanets should be widespread.
