The reason for the strangeness of this summary is that in order to rust, it needs two basic components: water and oxygen.

And CNN reported that scientists have found evidence to prove this, according to Sky News.

The Indian probe “Chandrayaan 1” revolved around the moon in 2008, and collected data that led to many discoveries in the following years, including the discovery of water molecules on its surface. The probe had technology designed by the US Aerospace and Space Administration (NASA) that could analyze the mineral composition of the moon.

When researchers from NASA and the Hawaiian Institute of Geophysics analyzed the probe data, they were stunned when they noticed signs of “hematite”, a form of iron oxide known as rust.

The researchers said that there are large amounts of iron-rich rocks on the moon, but that rust is only produced when the iron is exposed to oxygen and water.

“At the beginning, I did not fully believe it,” said NASA researcher Abigail Freeman. “It is assumed that rust should not be present in the moon according to its conditions.”

Not only is the moon empty of air, but its surface is covered with hydrogen that flows from the sun and is carried by the solar wind.

Rust occurs when oxygen removes electrons from iron, but hydrogen does the opposite, adding electrons, which means that rust is difficult to form.

“It is very confusing,” said lead author of the study published in the journal Science Advance, Shuai Li. “The moon is a tough environment for hematite.”

After months of continuous research, Lee and his colleagues at NASA were able to reach a theory that it is related to planet Earth.

They say that rust was present on the side of the moon closest to Earth, indicating that it is somehow connected to Earth.

They explained that the Earth is surrounded by a magnetic field and solar winds lead to the formation of a long magnetic tail, in which the moon enters for 3 days before its completion, and it takes 6 days to cross the tail and exit from the other side.

During this period, the magnetic tail submerges the moon with electrons, and hematite dust may settle on it, in a hypothesis that scientists believe could be a cause of rust on the surface of the moon.
