The swirly shades we see on the moon are known as a lunar mare, and they are the result of ancient lava from volcanic activity on the moon's surface. Such markings are absent on the moon's far side.
Computer models combined the various features, supporting the theory that lava flows from a huge impact on the moon once appeared on the Moon's face. Not only are the differences profound, but they are also reflected in the different geological structures on both sides of the Moon
Astronomers have long believed that the moon's face was covered in a sea of magma that cooled and softened the rocky terrain, resulting in the dark spots we see today.
The basin is a relic of one of the Moon's largest and oldest collisions. Simulations show that the SPA event, which occurred approximately 4.3 billion years ago, occurred at precisely the right time and in precisely the right place to initiate changes to only one side of the lunar mantle.
This concept also coincides with another enigmatic lunar distinction: several near-side regions are known to contain chemicals like potassium and phosphorus, as well as heat-producing substances like thorium and other rare earth elements. These components, collectively known as Procellarum KREEP terrane, or PKT, aren't found on the moon's far side.
However, the materials that the new study's researchers discovered spurring volcanic activity in their simulations on the near side of the moon and as a result of the impact are precisely the materials that the new study's researchers discovered spurring volcanic activity in their simulations on the near side of the moon and as a result of the impact.
The most ancient nearside volcanic plain erupted 200 million years after the impact events. Strong volcanic activity on the near side of the Moon persisted for up to 700 million years after the impact.
The interaction of this side of the Moon with the impact, according to scientists, is explained by the two places where the impact is focused on the transport of heat-producing substances and the slight changes in gravity.
The upper mantle in the southern hemisphere warmed in each scenario studied, and materials began to flow into the northern hemisphere through the near side. The upper mantle, on the other hand, has stayed too cold to discharge the same substance in the same manner. This disparity may have resulted in a perceptible asymmetry between the moon's two halves.
"Probably important unanswered subject in lunar science is how PKT came to be," Jones said. One of the most significant events in ,oon history is the South Pole-Aitken effect. This project blends the two, and I believe the results are intriguing."
