Water is not similar everywhere.

 Water is not similar everywhere. 

The water on Mars is not in the form that it is on Earth, say NASA scientists. The thing is that there are many forms of water in the universe what is different than we know that liquid. There are deep oceans on the icy moons like Ganymede and Europa. 

Those oceans on single icy moons are involving more water than on Earth. The icy moons like Enceladus have icy geysers. And that makes them interesting places. There is the possibility that some tiny, primitive organisms are living in those oceans. They might get their energy from the volcanic temperature that is created by the tidal forces of the giant gas planets. 

But the thing is that those oceans are different than oceans on Earth. The tidal waves are keeping those oceans liquid. And the thing is that the gravitation on those moons is weaker than on Earth. So the pressure in those oceans is lower. 

And that makes water more moving than it moves on Earth. The distance of water molecules in those oceans is higher. That means fiction is lower than it's on the Earth. So water moves more easily and the effect of tidal forces is higher than it's on the Earth 

When we are thinking water, we mean the chemical combination called H2O. But the form of the H20 can be very different than we ever imagine. Oxygen and hydrogen can be connected to other atoms and stored in molecules in stones. So the thing is that. Those gasses can locate on planets. Even there is no water or even atmosphere.  The thing is that planet can be full of water. And it can seem dry. In those cases, water can be connected to minerals. 

In some cases, water can easily separate from minerals simply by heating it. One of the minerals that seem dry but heat is releasing water vapor is copper sulfate. And on many other planets, the atmosphere can be so hot. That there are no water drops. That means the atmosphere can be full of vaporized water. But it cannot touch the surface of that planet. 

Also, the friction of the high-speed winds of the atmosphere of gas planets can keep water in vaporized form. Or the wind is breaking the ice so small bites that they are flowing at atmosphere which temperature is only a couple of kelvin. That kind of "smoke ice" (small particle ice) is found in the atmospheres of Uranus and Neptune. So the form of the water in other planets can be far away from what is on Earth. Also, the deep oceans of some planets can involve water. 

That pressed to solid form. Extreme pressure can form a thing called "hot ice". In those cases, pressure is the thing that denies the movement of the water molecules. That kind of situation can be on hot planets. And there is water that is far different than water is on our planet.
