Explanation: What spooky planet is this? Planet [6] Earth [7]  of course, on a
dark and stormy night in 2013 at Hverir [8] , a geothermally active area [9]
along the volcanic landscape [10]  in northeastern Iceland [11] . Geomagnetic
storms [12]  produced the auroral display [13]  in the starry night sky while
ghostly towers of steam and gas venting from fumaroles [14] danced against the
eerie greenish light. Tonight, there is also a chance for geomagnetic storms
[15] triggered by recent solar activity, so high-latitude skygazers should
beware. Ghostly shapes [16] may dance in your neighborhood [17]  pretty soon,
too.
