Scientists have discovered an unknown material on the moon’s largest crater, and they are not yet sure what to make of it.
The mysterious mass of material is found buried under South Pole-Aitken basin, the moon’s largest crater, and may contain substances from an asteroid that crashed into the Moon and created the crater, the statement quotes the Baylor University Study.
This crater cannot be seen from earth because it’s on the far side of the moon.
The Baylor University Study, “Deep Structure of the Lunar South Pole-Aitken Basin,” is published in the journal “Geophysical Research Letters.”
Researchers studied data obtained from the spacecrafts used for NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission.
According to James, the dense substance “whatever it is, wherever it came from” is weighing down the crater floor by half a mile.
“We did the math and showed that a sufficiently dispersed core of the asteroid that made the impact could remain suspended in the Moon’s mantle until the present day, rather than sinking to the Moon’s core,” James said.
According to their statement, there’s another possibility that the large mass might be a concentration of dense oxides associated with the last stage of lunar magma ocean solidification.
South Pole-Aitken Basin
The South Pole-Aitken basin is the largest and the oldest impact basin on the moon, according to NASA.NASA explains that the South Pole-Aitken basin is roughly 1,550 miles in diameter. This means it extends across almost the quarter of the moon’s surface.
“Stratigraphic relationships show that SPA is the oldest impact basin on the moon, but scientists are intensely interested in just how old it is. Lunar samples suggest that most of the major basins on the moon formed around 3.9 billion years ago in a period called the late heavy bombardment,” according to NASA.
