Recently, scientists found a massive metal structure buried deep beneath the lunar surface, below the Moon’s icy south pole. The structure’s dimensions are pretty impressive, being more significant than Denmark and stretching 290 kilometers below the surface. After the discovery, experts started theorizing. Most of them believe that the structure is residue left behind from asteroid impacts that occurred billions of years ago.
The metal lump was discovered by a team of researchers at Baylor University in Texas, by using data from NASA’s Gravity Recovery and Interior Laboratory and Lunar Reconnaissance Orbiter missions. The team focused on The South Pole-Aitken basin, which is the deepest crater on the Moon. It spans almost 2,000 kilometers across the Moon’s far side.
Since the basin is lumpy, experts have always thought it appeared after a powerful asteroid impact. After discovering that the gravitational pull rises around the basin, hinting that an extremely compact structure lays beneath it, scientists decided to investigate it more.
Asteroid Impacts Might have Caused The Massive Metal Structure Beneath The Moon’s Icy South Pole
Researchers used computer-generated simulations during the study. The result suggests that the asteroid involved in the impact must have had a hot core of molten iron and nickel that ended up beneath the lunar surface during the collision.
Dr. James, who led the study, said: “When we combined that with lunar topography data from the Lunar Reconnaissance Orbiter, we discovered the unexpectedly large amount of mass hundreds of miles underneath the South Pole-Aitken basin. One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the Moon’s mantle.”
However, this is not the only possible explanation. The mass could be a concentration of dense chemicals related to the formation of the Moon. During the early stages of the celestial object, its magma ocean solidified, forming rocks.
