During a solar flare, magnetic field lines can twist up and suddenly snap like rubber bands under tension, releasing huge quantities of fast-moving plasma into space in a spectacular burst called a coronal mass ejection (CME).
CMEs are the largest explosions in our solar system, roughly equal to the power in one billion hydrogen bombs!
If the CME is directed towards Earth, it can cause strong aurorae at Earth's magnetic poles, can damage satellites, and disrupt radio and electrical signals.
