Just read this and found it quite interesting.
Apparently we got missed by a huge sun-storm in july 2012.
In the article it says, that studies have calculated the amount of possible damge with up to 2.6 trillion $.
And accoirding to the article, events like that happen more often than scientists thought up to now. The chance that a storm like the one in 2012 will hit us in the next 10 years are about 1/8.
Pretty crazy in my opinion.
