The gigantic impact that explains the mystery of the two sides of the Moon

It was in the late 1950s and 1960s that Soviet and American missions revealed two very different faces of the Moon.

The visible face is covered by so-called lunar seas, which appear as large dark patches that reveal ancient lava flows. On the hidden face, however, these seas are barely visible.

The reason for this difference is a long-standing mystery.

But a new scientific study from the United States proposes an explanation to solve the riddle: a gigantic impact billions of years ago would have generated this difference.
