Several key conditions came together to create this award-winning shot. These included a dark night, few clouds, an epic auroral display, and a body of water that was both calm enough and unfrozen enough to show reflected stars. The featured skyscape of activity and serenity appeared over Iceland's Vatnajökull Glacier a year ago January, with the Jökulsárlón Iceberg Lagoon captured in the foreground. Aurora filled skies continue to be common near Earth's poles as our Sun, near Solar Maximum, continues to expel energetic clouds of plasma into the Solar System.

"if it had hit, we would still be picking up the pieces," said daniel baker, of the laboratory for atmospheric and space physics at the university of Colorado. "i have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did. if the eruption had occurred only one week earlier, Earth would have been in the line of fire."

with colleagues from nasa and other universities, baker has been studying the disaster that wasn't. if the coronal mass ejection (cme) had hit the Earth, it would have disabled "everything that plugs into a wall socket".

there would have been major disruption to all satellite communications and electrical fluctuations that could have blown out transformers in power grids. most people wouldn't have been able to turn on a tap or flush a toilet because urban water supplies largely rely on electricity.
