Today is the anniversary of an historic solar storm, the Carrington Event. On Sept. 2, 1859, a CME struck Earth’s magnetic field with such power that telegraph stations caught fire and people in Cuba read their morning newspapers by the red light of the aurora borealis. If a similar storm struck our planet today, it might cause trillions of dollars of damage to society’s high-tech infrastructure. Could the Carrington Event happen again? It almost did just a few years ago. Extreme solar storms–past, present and future–are highlighted on today’s edition of http://spaceweather.com.
As a reminder, a major CME would be as bad as an EMP attack. CMEs don’t destroy electronics like an EMP would, but they a large one can take down the power grid. Permanently.
