On the Moon “lunar swirls” are bright features that can be tens of miles across and appear as isolated individuals or in extensive groups or belts.

Lunar swirls are found where the lunar crust is magnetized, although not all magnetic areas have swirls. Furthermore, the bright areas in the swirls look to be less weathered than their surroundings.

Those observations have led to several hypotheses about how lunar swirls are formed and several ideas about the separate question of the origin of the magnetized crust.

Is it possible that these tattoo-like oddities might help sustain a human presence on the Moon?
