Glad you made this thread because I went on spaceweather yesterday and read their alert and was like... why isn't anyone talking about this!? Sounds
pretty serious. Unfortunately, I'm no expert and was hoping someone would have more info.
I wouldn't be surprised if the "big one" hit us pretty soon... unless someone more knowledgeable about solar flares can tell me otherwise? How likely
is it that the big one will hit us sometime this year or in 2013?
The following was issued by NASA today:
