How did Earth get its water? Missing link found!
According to recent study, Earth's water could have come into existence as a result of chemical interactions between hydrogen-rich atmospheres and magma oceans during planet formation. The new research from Carnegie Science's Anat Shahar and UCLA's Edward Young and Hilke Schlichting demonstrate based on exoplanet research that early in Earth’s existence, interactions between the magma ocean and a molecular hydrogen proto-atmosphere could have given rise to huge quantities of water. A study published recently in the journal Nature Astronomy suggested that volatile and organic-rich C-type asteroids may have been one of the primary sources of Earth's water. According to the researchers, based on the study of common exoplanets discovered orbiting distant stars, the rocky material that collided to form the growing planet was completely dry, but the interactions between the molecular hydrogen atmosphere and the magma ocean would generate plenty of water.
