   Explanation: This sight was worth getting out of bed early. Two years
   ago this month, Comet C/2020 F3 (NEOWISE) rose before dawn to the
   delight of northern sky enthusiasts awake that early. Up before sunrise
   on July 8th, the featured photographer was able to capture in dramatic
   fashion one of the few comets visible to the unaided eye this century,
   an inner-Solar System intruder that has become known as the Great Comet
   of 2020. The resulting video detailed Comet NEOWISE from Italy rising
   over the Adriatic Sea. The time-lapse video combines over 240 images
   taken over 30 minutes. The comet was seen rising through a foreground
   of bright and undulating noctilucent clouds, and before a background of
   distant stars. Comet NEOWISE remained unexpectedly bright until 2020
   August, with its ion and dust tails found to emanate from a nucleus
   spanning about five kilometers across.
