Coronal Mass Ejections (CMEs) are massive bursts of solar wind and magnetic fields rising above the solar corona or being released into space. These events can eject billions of tons of coronal material and carry a magnetic field that can interact with the Earth's magnetosphere, potentially causing geomagnetic storms.
When a CME reaches Earth, it can disrupt satellite operations, power grids, and even create beautiful auroras. Understanding CMEs is crucial for space weather forecasting, as they can have significant impacts on technology and infrastructure on our planet.
