[00:00:00]Did you know a solar storm once made telegraph wires catch fire while operators kept working on pure electromagnetic energy? September 1st, [music] 1859.

[00:00:09]British astronomer Richard Carrington was sketching sunspots through his telescope when he witnessed something extraordinary. A brilliant white light erupted from the sun's surface, the largest solar flare ever recorded by human eyes. 18 hours later, the charged particles slammed into Earth. Telegraph systems across the world went haywire.

[00:00:29]Wires sparked and burst [music] into flames. Telegraph poles caught fire.

[00:00:33]Operators received electric shocks. But here's the incredible part. Some telegraph operators disconnected their power sources entirely and kept working.

[00:00:42]The aurora was so intense, it generated enough electromagnetic energy to power the telegraph lines. Messages traveled from Portland to Boston on nothing but space weather. The northern lights appeared as far [music] south as the Caribbean. People in the Rocky Mountains woke up thinking it was dawn and started making breakfast. One newspaper called it [music] "The greatest disturbance of the electric telegraph ever recorded."

[00:01:06]Today, a Carrington-level event would our satellites, internet, and power grids. Nature's reminder that we're not as safe as we think.
