Water Outside the Earth - (SCI-7)

Introduction

''Hydrogen, Helium and Oxygen are the most abundant elements in the Universe”. Taken from “Water, A Very short Introduction”, by John Finney.

Inert Helium

Because helium is inert, this leaves hydrogen and oxygen to do most of the mingling. So it is no surprise that water, H₂O is one of the most abundant substances in the cosmos.

On Earth

In relation to the Earth, H₂O is the most substance on its surface.

Outside Earth

In the cosmos the most abundant substance is H₂, that is Hydrogen gas, with the next most abundant substance in the cosmos being water - H₂O.

Outside the Earth water is found as a gas in interstellar space and also as ice on some of the other planets and moons in our solar system.

It has also been found in the atmosphere of some stars, including our sun, and it is also abundant as a solid ice phase in the cores of comets and in the surface particles of asteroids and meteorites.

Summary

Surprise, I didn’t think that water was so abundant. According to science it really is, and this further confirms that water is something special and is very much related to creation and life. We can even say no water, no creation that can be sustained.
