Sonia Tikoo explores the unresolved history of the Moon’s magnetic field. Lunar samples indicate a strong early field followed by a much weaker field that persisted far longer than expected. The discussion weighs proposed dynamo mechanisms, paleomagnetic measurements and the difficulty of explaining both the field’s early strength and its long-lived weak tail.

Steve Jacobsen describes how laboratory experiments reproduce the extreme pressures and temperatures found inside planets. He explains how the behaviour of minerals under those conditions informs models of planetary interiors and discusses work at the NSF Center for Matter at Atomic Pressures.
