Astronomers at Baylor University have just found something on the Moonâs largest crater that has left them confused and wondering how exactly it got there in the first place.
According to Futurism.com:
âA team of astronomers found a âlarge excess of massâ under the Moonâs largest crater, the Aitken basin â likely a relic from an ancient asteroid impact event, but perhaps something much stranger.â
A sub-surface metallic anomaly on the moon? Somebody call dr. Heywood Floyd, STAT!https://t.co/DIVmrFKv2i

Lead researcher Peter B. James noted:
âImagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. Thatâs roughly how much unexpected mass we detected.â
So where exactly did this enormous mass come from? There are two theories, but no solid answers just yet, Phys.org reports:
âThe dense massâwhatever it is, wherever it came fromââis weighing the basin floor downward by more than half a mile, (James) said. Computer simulations of large asteroid impacts suggest that, under the right conditions, an iron-nickel core of an asteroid may be dispersed into the upper mantle (the layer between the Moonâs crust and core) during an impact.
âAnother possibility is that the large mass might be a concentration of dense oxides associated with the last stage of lunar magma ocean solidification.â

The Moon crater where the anomaly was found is the largest preserved crater in the solar system, making it an object of fascination for astronomers. Dr. James called the crater basin âone of the best natural laboratories for studying catastrophic impact events, an ancient process that shaped all of the rocky planets and moons we see today.â
Researchers found the metallic mass thanks to space probes and other spacecraft that have been taking photographs of the Moon, CNN notes:
âThe researchers from Baylor used various sets of data collected from space crafts that measure the gravity around the moon, and compared them to maps and imaging of the moonâs surface. As a result, they found a dense metallic mass pulling down on the floor of the basin.â
This new information could well help explain the formation of various celestial bodies in our solar system, according to National Geographic:
ââItâs just so mysteriousââ says Sara Mazrouei of Western Universityâs Center for Planetary Science and Exploration, who was not involved in the work. And by improving our understanding of this structure, scientists hope to better understand the formation of bodies throughout our celestial family.â
Sadly, the casual stargazer cannot see the crater in question from Earth, as itâs literally on the far side of the Moon. So, for now, weâll just have to content ourselves with the incredible images coming from NASA.
