Coronal mass ejections (CMEs) from the Sun can cause geomagnetic storms when they interact, sometimes leading to stunning auroras or disruptions in technology. In May 2024, a collision of two CMEs resulted in a powerful storm, sparking interest in studying these events. As the Sun approaches its solar maximum, understanding CME interactions becomes increasingly important for protecting infrastructure—a subject of study for researchers at institutions like the University of Michigan, who are working to improve space weather predictions.
