An Enigmatic Unseen Influence Is Producing Water on the Moon.

Astronomy, Planetary Science / Marcílio Santos

While we are aware of the existence of lunar ice, its origin remains somewhat uncertain. A recent investigation proposes that streams of electrons, which indirectly originate from both Earth and the Sun, are playing a role in the creation of frozen water on the Moon’s surface. These electrons impact the Moon when it traverses through
