It is a well-known fact that the Earth is 70% water, and that our atmosphere is also full of it.
But can the same be said for the moon?
At first, it was believed that there was no water on the moon’s surface, because the environment would not allow it (no atmosphere means the water evaporates much quicker than it does on Earth).
However, it was found in 2008 that some amounts of water did exist on the moon’s surface at its poles.
Its existence, according to an article by Forbes, doesn’t have a concrete origin, but it’s existence has since been 100% confirmed by many probes.
