On March 13, 1989, the lights went out across Canada and the eastern seaboard of the United States. One of the most serious power grid failures in American history was caused by a magnetic storm. NOVA explores one of the most serious threats to life.
On March 13, 1989, the lights went out all across Canada and the eastern seaboard of the United States, as far south as New York. The most serious power grid failure in American history was caused by a magnetic storm in the earth's upper atmosphere, itself triggered by the eruption of a huge flare from the surface of the sun. Unusual as this event may seem, many scientists today are beginning to worry that it may be a harbinger of things to come, and that changes to the planet's magnetic field could make us ever more vulnerable to deadly radiation from space.
