Will The Sun's Magnetic Poles Flip This Year?
Oct 31, 2026 · 22m
Summary
PBS Space Time explores the unexpected intensity of the current solar cycle, which is far stronger than predicted despite historical trends toward weakening. The episode details the solar dynamo mechanism, explaining how differential rotation and magnetic buoyancy generate sunspots and coronal mass ejections. It also examines how scientists use geological records to track ancient solar activity and discusses why forecasting the strength of future cycles remains challenging due to complex magnetic reconnection processes.
