In spite of what fantasists, conspiracy theorists, incompetent interpreters of the Mayan calendar and Roland Emmerich suggested, the world did not end on the 21st of December 2012. But earlier that year, on the 23rd of July, the world really did come extremely close to what NASA estimates would have been a $2 trillion economic and technological disaster.

A coronal mass ejection — a huge burst of hot plasma — from the surface of the sun exploded into space. And if it had hit the Earth, the burst of charged particles would have severely damaged Earth's infrastructure of satellites, computers, the electrical grid, medical equipment, and smartphones. Unshielded electric circuits would be fried.

"If it had hit, we would still be picking up the pieces," Daniel Baker, of the Laboratory for Atmospheric and Space Physics at the University of Colorado, told The Guardian. He adds that "[i]f the eruption had occurred only one week earlier, Earth would have been in the line of fire."

The sun periodically blows off huge quantities of plasma. The last time Earth was struck was 1859, an event referred to in astronomy as The Carrington Event for its discoverer Sir Richard Carrington. That was before we came to rely on electrical equipment and computers for our modern way of life. But even then, it caused telegraph lines to spark enough to set fire to some telegraph offices. And the Northern Lights, were visible as far south as Cuba.

Nobody knows when such an event will occur again, but FEMA warns Americans should be prepared for the possibility, and recommends a series of steps for preparation, including making back-up copies of important digital data and information, keeping your car's gas tank at least half full, and filling plastic containers with water and placing them in your refrigerator or freezer.
