Metal or Magma?

The anomaly’s origins: Baylor University’s Peter B. James suggests the mass could be metallic remains of an asteroid or oxides formed during the Moon’s magma ocean crystallization.

Hawaii Comparison

Gigantic proportions: “Imagine a pile of metal five times the size of the Big Island of Hawaii buried underground,” James explains. That’s the magnitude of the anomaly detected.

GRAIL’s Contribution

NASA’s eyes in the sky: The discovery was made possible by NASA’s GRAIL mission, which measures subtle changes in the Moon’s gravitational field to reveal its internal composition.

Lunar Interior Clues

Unraveling the Moon’s history: Data from the anomaly offers new insights into the Moon’s mantle and the aftermath of ancient cosmic collisions.

Cosmic Impact

A tale of asteroids: If the mass is indeed from an asteroid, it highlights the Moon’s violent history and its role as a cosmic shield for Earth.

Future Mysteries

What’s next?: With NASA’s Artemis program planning further lunar exploration, the South Pole-Aitken Basin may soon reveal even more secrets of our celestial neighbor.
