   Explanation: Did you see last night's aurora? This question was
   relevant around much of the world a few days ago because a powerful
   auroral storm became [4]visible unusually far from the Earth's poles.
   The cause was a giant [5]X-class solar flare on Tuesday that launched
   energetic [6]electrons and protons into the [7]Solar System, connecting
   to the Earth via our planet's [8]magnetic field. A [9]red glow of these
   particles striking [10]oxygen atoms high in [11]Earth's atmosphere
   pervades the frame, while [12]vertical streaks dance. The [13]featured
   video shows a one-hour timelapse as seen from [14]Cortina d'Ampezzo
   over [15]Alps Mountain [16]peaks in northern [17]Italy. Stars from our
   [18]Milky Way Galaxy dot the background while streaks from airplanes
   and satellites punctuate the foreground. The [19]high recent activity
   of [20]our Sun is likely to continue to produce [21]picturesque auroras
   over Earth during the next year or so.
