The Moon is our nearest neighbour, and the only other planetary body humans have ever set foot on. We have been exploring the Moon via manned and robotic missions for more than half a century, but there are still many parts of its history that we cannot explain. Given the relatively small size of the Moon, it is reasonable to assume it cooled down very quickly and has been geologically ‘dead’ for much of its history. However, a huge number of observations refute this assumption. Magnetic measurements on Apollo samples highlight that the Moon was able to generate its own magnetic field that was, for a time, even stronger than Earth’s magnetic field today. New chemical data from the Chinese Lunar Exploration Program suggests the Moon has had active volcanism, with lava flowing onto the surface for more than 3 billion years. In this talk, the speaker will explore some newly revealed links between the volcanic and magnetic history of the Moon and discuss how the upcoming Artemis missions can help us to understand more about some of the Moon’s most mysterious behaviour.
ISSI warmly congratulates Claire Nichols, ISSI Johannes Geiss Fellow 2026, on the publication of her new paper in Nature Geoscience: “An intermittent dynamo linked to high-titanium volcanism on the Moon.”
The study, led from the University of Oxford and based on analyses of samples returned by the Apollo program, resolves a decades-long debate about the strength of the Moon’s ancient magnetic field.
