Magnetic Anomalies on the Moon
Graduate Student, Johns Hopkins University Applied Physics Laboratory
Swirls are a unique class of lunar features. They occur across all types of terrain on the Moon and are associated with strong magnetic anomalies. Although the Moon does not currently have an active magnetic field like Earth, it may have had one in the past. The current magnetic anomalies may be left over from that time. Magnetic fields can provide radiation protection from the solar wind, influencing physical and chemical properties of lunar soil.
