Lunar Swirls
Lunar swirls are among the Moon's most beautiful and bizarre features. These bright, sinuous patterns look like they are painted across the flat mare terrain and up and over the tall peaks. Some scientists believe they may result from local magnetic field anomalies that shield the surface from the solar wind striking the lunar soil.
