Our Moon has two sides, and they are very different. More recently, water has been found on the visible side of our satellite. It is not rivers or lakes, but a very small amount of water in the lunar soil. There is more in the Sahara Desert. Nevertheless, the discovery is interesting, but what is particularly interesting is where water comes from where it was thought there was none.
How Water Appeared on the Moon
Clearly, water in any state must evaporate when exposed to the sun.
This means that there is a constant source feeding the moon with moisture. It could be small meteorites, because meteoroid matter or comets have a decent amount of ice. There is a theory that a meteorite was the cause of life on Earth.
Or it was the solar wind. From the Sun moves a stream of fast particles, which in interaction with the lunar soil as a result of chemical reactions can form water.
Across the Universe.
But water isn't just on the Moon. It is actually present in the entire solar system and beyond.
For example, Mercury. The planet is very close to the red-hot Sun. With the help of telescopes, deposits of water ice have been discovered here. And there's lots and lots of it. On hot Mercury, where you'd think there wouldn't be anything like it. Except for steam.
On Mars real underground lakes were also found. And they consisted not of ice, but of water in liquid form. This is a kind of strong salty broth. After all, at such a depth and at such a temperature as on Mars, liquid normal water simply cannot exist.
Saturn's satellite Enceladus is hardly a glass ball. It is covered with an ice crust, and ice geysers hundreds of kilometers high pour out of it. Cryovolcanism is developed on the satellites of Uranus and Neptune. This is when hot water mixed with ice, rocks and soil instead of lava flows out of volcanoes.
Water creates amazing phenomena in space. And all the water on our planet is most likely of extraterrestrial origin and its true age cannot be calculated.
If you look into deep space, you'll find that there's a lot of water there, too. Hydrogen is the most abundant element, and oxygen is also abundant. Molecular clouds of water form in places where they join together. They are very highly discharged and represent a vacuum, a void.
You could say that water literally unloads us in outer space. Everywhere. And if we consider that water is the natural environment for the origin of life, then we are quite optimistic about it.
