In September 1859, two telegraph operators disconnected their batteries. Their messages kept moving. A massive solar storm had turned Earth's magnetic field into an unexpected source of electricity.

The Carrington Event revealed an invisible connection between the Sun and human technology — one that still threatens our electrical grids today. ─────────────────────────────── **IN THIS EPISODE** — The mysterious solar flash observed in September 1859 — Telegraph lines operating without batteries — The magnetic storm that illuminated skies across the world — What a Carrington-level event could mean for modern civilization **SOURCES** — Carrington & Hodgson, Monthly Notices of the Royal Astronomical Society (1859) — Green & Boardsen, NASA historical research on the 1859 storm — Hayakawa et al., historical geomagnetic storm research (2019) — Wolff et al., polar ice-core analysis (2012) ─────────────────────────────── Narration in this episode is AI-assisted.
