   Explanation: Comet NEOWISE has been wowing photographers around much of
   the world during dawn and dusk, at the margins of [6]day and night. For
   the most [7]northern residents of planet Earth, however, the comet
   circles the [8]North Star and [9]never sets. The night part of this
   circular arc is apparent in the featured composite of images assembled
   from a [10]webcam located at a ski resort in the [11]Swiss Alps. Images
   were selected at 30-minute intervals throughout the night from July
   12th -13th. Comet NEOWISE (C/2020 F3) will [12]continue to become more
   accessible to northern hemisphere observers as its [13]motion places it
   higher in the sky each evening after sunset over the next few weeks, as
   it begins its outbound journey. As with all comets, departure from the
   inner [14]Solar System comes with [15]inevitable fading. Binoculars are
   the best way [16]to find and observe the comet visually.
