    [2]The featured image shows steam rising from several separated vents
   at Hverir, a geothermally active field in Iceland. Green aurora rage in
        the background. Please see the explanation for more detailed
                                information.

   Explanation: [5]What spooky planet is this? Planet [6]Earth of course,
   on a dark and stormy night in 2013 at [7]Hverir, a geothermally active
   [8]area along the [9]volcanic landscape in northeastern [10]Iceland.
   Triggered by solar activity, [11]geomagnetic storms produced the
   [12]auroral display in the starry night sky. The ghostly towers of
   steam and gas are venting [13]from fumaroles and danced against the
   eerie greenish light. For now, auroral apparitions are increasing as
   [14]our Sun approaches a [15]maximum in its 11 year solar activity
   cycle. And pretty soon, [16]ghostly [17]shapes may [18]dance in your
   neighborhood too.
