Scientists can't explain mysterious large mass discovered on Moon

Scientists can't explain mysterious large mass discovered on Moon”

Scientists have said that the anomaly beneath what is considered the largest crater in our solar system, may contain metal from an asteroid that crashed into the moon and formed the crater.

The basin itself is thought to have been created about 4 billion years ago, making South Pole-Aitken the largest preserved crater in the solar system.

On the far side of the moon, buried nearly two hundred miles under the South Pole-Aitken basin (the largest preserved crater in our solar system), is a mysterious mass. Peter B. James and his team of scientists from Baylor University believe it could be the metal core of an asteroid which head-butted the moon and left that 1,242-mile-wide crater behind.

Researchers led by Peter James from Baylor University, Texas, were studying the structure of the South Pole-Aitken Basin.

To measure subtle changes in the strength of gravity around the Moon, Dr. James and colleagues analyzed data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission.

Unfortunately the crater - and the mysterious substance below - aren't visible to mere earthbound humans, since they're on, literally, the far side of the moon. The low center is dark blue and purple.

The Chinese lander Chang'e-4 and its Yutu-2 rover are now exploring the Von Karman crater within the South Pole-Aitken basin, and NASA also wants to target the South Pole for future exploration. Beneath this basin lies a odd anomaly-an excess of mass extending at least 300 kilometers down, more than 10 times the depth of the Earth's crust.

The anomaly - "whatever it is, wherever it came from", James added - is weighing down the basin floor by more than half a mile.

Baylor scientists believe the mass may also be suspended iron-nickel core from an asteroid that previously impacted the moon's surface.

Another explanation is that, following the impact that formed the basin, a huge ocean of metal-rich magma pooled inside of the lunar crust and solidified into a dense slab. [NASA/GSFC/Arizona State University].The lunar magma ocean solidification is a hypothesis that explains the early evolution of terrestrial planets, according to Science.gov The hypothesis that explains how the terrestrial planets reach their long-term solid-state planet dynamics is however poorly understood, according to the portal. This, according to researchers, is an anomaly that exists on the surface because of metallic remnants dislodged from the core of the massive impact that formed the South Pole-Aitken (SPA) basin. This is an impact crater that stretches about 1,600 miles in diameter.

Additional research and missions will be needed to confirm the presence of asteroid deposits beneath the South Pole-Aitken basin.

The far side of the moon is hiding a colossal secret beneath its airless, pockmarked surface.
