Water on celestial bodies across the Solar System.

Does water exist anywhere else in the solar system?
The answer is Yes!
A mighty yes!

About 70% of our planet Earth consists of water. It is said that life was first originated in water.
And, the possibility of finding water on other planets in the solar system would lead to another question.
Is there life else where in the Universe.
The answer is obviously yes. But, let's get back to the topic.

It has been observed that surface water once covered large areas of surface of planets, Venus and Mars.
The planet Mars has huge ridges in the surface indicating that Mars once had huge river systems.
Mars is said to have polar ice-caps where water is found in a solid form.

The next possibility of finding water in our solar system is in a moon of our biggest planet, Jupiter.
Yes.
Europa, the moon of Jupiter is said to have huge deposits of water.
Europa is said to have more water than the water present in the oceans and seas of earth.
Yep.
Amazing, ain't it?

Let's come to the gas giants, Jupiter and Saturn.
Neptune is said to have plenty of ice and water vapour.
But, the chances of water to be present in a liquid form given that pressure and temperature is quite less.
Jupiter, with it's massive size is said to comprise of many layers.
It is possible that the conditions on one of those layers may resemble the conditions on our planet and that water could exist there.


Now, the ice-giants.
Yep, Ice giants.
Uranus and Neptune are the ice-giants of our solar system. They're made up of methane, ammonia and water which are frozen.It is said that the middle layers may be actually vast layers of water and ammonia.

Oh and we're not done yet.
What about the comets and asteroids? Ever wondered what they're made up of?
Answer : Ice.
Yep, ice. Ceres, a lone dwarf planet might contain water-ammonia ocean beneath it's icy exterior.
So, we're not just the only ones to have water.
