"The Carrington Shock – The day the sun destroyed the telegraph and lit the sky" recounts the massive geomagnetic storm of 1859. Astronomer Richard Carrington observed a white light flare on the sun, and hours later, the Earth was bombarded with charged particles. Auroras were seen as far south as the Caribbean, and telegraph systems across Europe and North America failed, sparking fires and shocking operators. Science historian Sarah Nova explains the physics of coronal mass ejections and investigates what would happen if a similar event struck today. In 1859, it was a curiosity; today, it would fry satellites, the internet, and power grids, potentially sending civilization back to the dark ages for years. "The Carrington Shock" is a thrilling blend of history and warning. It highlights the extreme fragility of our high-tech world and reminds us that we live in the atmosphere of a volatile star. It is a story of the most powerful storm in recorded history, one that made the night as bright as day.
