Now You Know: Where does the water on the earth come from?

Synopsis

Water on Earth has a complex history, with evidence suggesting that it once existed in the planet's atmosphere before being stripped away by solar winds. This phenomenon raises critical questions about the origins of Earth's water. Scientific research indicates that water may have been delivered to Earth through comet impacts and volcanic activity during the Hadean and Archean eons. By examining geological and astronomical data, the documentary provides insights into the processes that shaped the planet's hydrosphere and the vital role water plays in sustaining life.
