Scientists have unraveled the mystery of the appearance of patterns on the surface of the moon

Ученые разгадали загадку появления узоров на поверхности Луны

American researchers said that the emergence of patterns on the surface of the moon is associated with the lava tubes.

Scientists from Rutgers University in the US said that they were able to solve the riddle of the mysterious occurrence of “eddies” on the surface of the moon that can be seen with a telescope. According to researchers, these patterns are associated with lava tubes, which are located under the surface of the satellite.

Previously, scientists have found that the location of the lunar vortices coincides with areas of high magnetic field strength of the moon. However, the satellite of the Earth is not rotating core, which could generate a global magnetic field. Despite the fact that each such vortex is associated with a magnetic anomaly, not every such region there are such patterns. In addition, they are less susceptible to weathering than the surrounding regolith, with the result that retained their relatively high albedo.

In the study, researchers conducted a computer simulation, which showed that such turbulence should occur in the immediate vicinity of the source of the magnetic field or directly above it. These sources are likely to lie not very deep and are lava tubes – channels that are formed by uneven cooling of the lava, satyavrata on the slopes of the volcano. Such structures were formed on the moon three or four billion years ago.

When heated to 600 degrees Celsius and subsequent cooling of the lunar rock in the presence of a magnetic field and in the absence of oxygen become magnetized. This is because high temperature leads to the destruction of minerals and the release of a prisoner in their iron atoms which are oriented along the lines of the external magnetic field. The lunar magnetic field disappeared in about one billion years ago, which allows you to set a minimum age of vortices.
