   Explanation: Gusting solar winds and blasts of charged particles from
   the Sun resulted in several rewarding nights of auroras back in 2014
   December, near the peak of the last 11-year solar cycle. The featured
   image captured dramatic auroras stretching across a sky near the town
   of Yellowknife in northern Canada. The auroras were so bright that they
   not only inspired awe, but were easily visible on an image exposure of
   only 1.3 seconds. A video taken concurrently shows the dancing sky
   lights evolving in real time as tourists, many there just to see
   auroras, respond with cheers. The conical dwellings on the image right
   are tipis, while far in the background, near the image center, is the
   constellation of Orion. Auroras may increase again over the next few
   years as our Sun again approaches solar maximum.
