It all began with a molecular cloud.
on Saturday has revealed how water came to be on our humble planet, and it is fascinating.It all began with a cloud. That cloud was mostly hydrogen, water's main component, with a touch of helium, oxygen, and carbon.The oxygen in the cloud then came into contact with a dust grain. It froze and adhered to the surface.
Through this interaction, water ice was then formed. But that's just the first step called the cold phase. At this stage, the water ice that formed in step one and was transformed into gas in step two goes back to being ice in the coldest reaches of the protoplanetary disk. Dust grains are once again covered in an icy mantle.Now comes step four when we see the Solar System begin to resemble a more fully-formed system. Planets, asteroids, and comets, start taking shape and placing themselves in their assigned orbits.
