Scientists have discovered that our Moon is rusting.
The scientific name for rust is iron oxide and it requires the presence of water and oxygen to form.
Rust on the surface of Mars is what gives it its reddish colour. This makes scientists believe that the planet once had water and oxygen on its surface.
The discovery of rust on the Moon is surprising because the Moon has no air or liquid water on it.
However, rust on the Moon can be explained in a number of ways, the scientists discovered.
Although the Moon does not have an atmosphere, it does have tiny bits of oxygen present because of the Earth’s magnetic field.
Oxygen can travel from the planet to the Moon by riding Earth’s magnetic field.
Another reason why the rust could be present is because of the ice that is present on the Moon, found under lunar craters on the Moon’s far side.
