Solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce ‘sparks’ that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to new research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the moon and solar system.
