A new theory on the origin of water on Earth Astrophysicists propose an innovative explanation for the origin of water on planets, without resorting to violent impacts by asteroids or comets. A study published in Astronomy & Astrophysics, led by Paris Observatory, shows that water could form directly in the protoplanetary disks surrounding young stars, thanks to natural chemical processes. This discovery overturns traditional models and offers new perspectives for understanding the diversity of planetary environments and the emergence of habitability. https://www.myscience.fr/news/2024/a_new_theory_on_the_origin_of_water_on_earth-2024-myscience
