Scientists Detect First-Ever Switchback in Earth’s Magnetosphere | Space Weather Breakthrough” A groundbreaking discovery has revealed a rare “switchback” event inside Earth’s magnetosphere for the first time. Switchbacks are sudden reversals in magnetic field lines that change the flow of charged particles in the solar wind. Until now, they had only been observed near the Sun by missions like the Parker Solar Probe. Detecting them around Earth opens a new window into how solar energy interacts
