On March 13, 1989, a powerful solar flare and coronal mass ejection (CME) from the Sun caused one of the most intense geomagnetic storms in modern history—leading to a massive blackout in Quebec, Canada and disrupting satellites, communications, and even the space shuttle Discovery. 🌍⚡In this video, we break down:

• What caused the 1989 geomagnetic storm
• How solar activity affects Earth's power grid and satellites
• The science behind auroras and solar flares
• What we’ve learned since—and could it happen again?
