Like many Victorian gentlemen of means, Richard Carrington did not need to sully himself with labor; instead, he turned his energies to the study of natural philosophy. It was the field of astronomy to which Carrington would apply himself, but unlike other gentlemen of similar inclination, he began his studies not as the sun set, but as it rose. Our star held great interest for Carrington, and what he saw on its face the morning of September 1, 1859, would astonish him. On that morning, as he sketched an unusual cluster of sunspots, the area erupted in a bright flash as an unfathomable amount of energy stored in the twisted ropes of the Sun’s magnetic field was released, propelling billions of tons of star-stuff on a collision course with Earth.

Carrington had witnessed a solar flare, and the consequent coronal mass ejection that would hit Earth just 17 hours later would result in a geomagnetic storm of such strength that it would be worldwide news the next day, and would bear his name into the future. The Carrington Event of 1859 was a glimpse of what our star is capable of under the right circumstances, the implications of which are sobering indeed given the web of delicate connections we’ve woven around and above the planet.
