It is a known fact that the Moon affects the tides of the sea. The vast oceans on Earth's surface are all affected by the Moon's gravitational pull. This is common knowledge with school textbooks around the world that teach this scientifically proven fact that was observed many centuries before the scientific era.
But our only natural satellite can also "suck" water for itself. A study indicates that water on the Moon may have originally been on Earth!
There are many theories about how water molecules reach the surface of the Moon. Suggestions such as the impact of water-rich asteroids and comets have been suggested to explain the presence of water on the Moon.
But this new study highlights an interesting idea. The study suggested that hydrogen and oxygen ions escaping from Earth's atmosphere would recombine to form water on the Moon's surface.
But how did the unthinkable actually happen?
Research suggests that this process takes place when the Moon passes through the tail of the Earth's magnetosphere (a teardrop-shaped bubble formed by the Earth's magnetic field).
When the solar wind affects the Earth's protective magnetic field, some lines of magnetic field are broken. As the Moon passes through the tail of the magnetosphere, some of the fractured magnetic field lines will become fixed. This results in what is known as a "shower" of hydrogen and oxygen ions. These ions combine to form water on the Moon's surface.
This study was published in the journal Scientific Reports.
