According to a Baylor University study, a mysterious mass has been discovered hundreds of miles beneath the largest crater in our solar system, the Moon’s South Pole-Aitken basin.
Lead author of the study Peter B. James says the mass is approximately five times the size of Hawaii, and may contain metal from the asteroid that formed the crater.
James says the basin is one of the best natural laboratories for studying catastrophic impact events which shaped all of the rocky planets and moons to this day.
