Coronal mass ejection

A coronal mass ejection (CME) is a massive burst of plasma and magnetic field expelled from the solar corona into the heliosphere, often traveling at speeds exceeding 1000 km/s. Unlike the steady solar wind, CMEs are transient eruptions driven by the catastrophic release of magnetic energy through magnetic reconnection and ideal instability. When Earth-directed, they produce geomagnetic storms that disrupt satellites, power grids, and communication systems.

The coronal mass ejection is the solar system's temper tantrum — a reminder that the Sun is not a passive furnace but a magnetically active dynamo capable of hurling billions of tons of plasma across interplanetary space.
