Scattered across the Moon are peculiar, snaking bright swirls. Nobody knows what created them. Comet impacts, maybe?

A new paper suggests a different answer: Lunar swirls might trace underground rivers of frozen, magnetic lava.

Moon ‘swirls’ could be magnetized by unseen magmas - The Source - Washington University in St. Louis

In a laboratory setting, experimental petrologists at Washington University in St. Louis recreated the magnetizing reactions that could be causing the mysterious, light-colored features on the Moon’s surface, known as lunar swirls.

I love that the Moon still holds so many mysteries.

Next year, the Lunar Vertex mission will send a little rover driving across Reiner Gamma -- the most prominent of the lunar swirls -- to figure out what the heck is going on there.

Lunar Vertex

Lunar Vertex will be the first mission to carry out a comprehensive study of lunar magnetic anomaly and the associated swirl and mini-magnetosphere.
