Not supporting the "thousands of years" part of your parent's comment, but the moon gets hit by solar wind; "electrostatic charging caused the dust to levitate"

Not supporting the "thousands of years" part of your parent's comment, but the moon gets hit by solar wind; "electrostatic charging caused the dust to levitate" [0]. Quote from "Moon Storms" [1]: "To everyone's surprise," says Olhoeft, "LEAM saw a large number of particles every morning, mostly coming from the east or west--rather than above or below--and mostly slower than speeds expected for lunar ejecta." What could cause this? Stubbs has an idea: "The dayside of the moon is positively charged; the nightside is negatively charged." At the interface between night and day, he explains, "electrostatically charged dust would be pushed across the terminator sideways," by horizontal electric fields.
