The European Space Agency (ESA) has launched the Smile mission, a three-year project aimed at studying geomagnetic storms and their effects on Earth. These storms are caused by solar activity and can disrupt satellite operations, power grids, and communication systems. The mission seeks to better understand these phenomena to help anticipate risks and protect space-based technologies. A significant focus of Smile is on geomagnetic reversals, events in which the Earth’s magnetic poles switch places. During these reversals, the magnetic field weakens and becomes more complex, forming multiple poles rather than the familiar north and south. Researchers at the Helmholtz Centre for Geosciences (GFZ) in Potsdam used paleomagnetic data—information about Earth’s magnetic field from ancient rocks—to build a model of the Earth’s magnetic field during the Matuyama-Brunhes reversal. This event occurred about 780,000 years ago and marked the last time the Earth’s magnetic poles reversed. Using this model, scientists created a video that visually illustrates how the intensity of the magnetic field changed across the Earth’s surface during the reversal. The video provides a dynamic representation of how the field evolved over time, offering new insights into past magnetic behavior. To complement the visual representation, a six-voice musical piece was composed using three violins and three violoncellos. The music was designed to reflect the complexity and evolution of the magnetic field during the reversal. The video was produced by ESA with contributions from several researchers and artists. Sanja Panovska and Ahmed Nasser Mahgoub from GFZ provided scientific input, while Maximilian Arthus Schanner from GFZ handled the animation. Klaus Nielsen from DTU and Maple Pools, along with Max Schanner, contributed to the sound design. Guram Kervalishvili from GFZ served as the executive producer. The project received special thanks to Martin Rother from GFZ for his support. This collaboration between science and the arts highlights the interdisciplinary nature of modern space research, using creative methods to explain complex natural processes. The Smile mission and its accompanying video not only advance scientific understanding but also engage the public in the fascinating story of Earth’s magnetic field.
