On September 2, 1859, Earth was struck by the most powerful geomagnetic storm in recorded history, triggered by a massive solar flare during what became known as the Carrington Event. The storm was so intense that telegraph systems around the world sparked, caught fire, and transmitted messages without batteries—powered entirely by auroral currents.
Brilliant auroras lit up skies as far south as the Caribbean, astonishing observers in an era before electricity dominated daily life. Scientists soon realized that the Sun could unleash forces capable of disrupting technology on a global scale.
Today, the Carrington Event remains a sobering benchmark for solar activity—reminding us how vulnerable modern infrastructure is to space weather.
