Coronal mass ejections (CMEs) move from the surface of the Sun towards Earth through space. Top: CME is generated as an outflow of plasma and magnetic fields from the Sun, moving through space to Earth over a matter of hours. Bottom: The magnetic fields of the CME and outflowing solar wind interact with Earth’s magnetic field, which shields it from greater effect.
