   Explanation: [5]Comet-like plumes are blowing over the volcanic peaks
   of [6]Mount Etna in this wintry mountain-and-skyscape from planet
   Earth. The stacked and blended combination of [7]individual exposures
   recorded during the cold night of [8]January 23, also capture naked-eye
   Comet ZTF just above Etna's snowy slopes. [9]Of course increasing
   [10]sunlight and the solar wind are responsible for the comet's
   greenish coma and broad dusty tail. This weekend Comet ZTF is dashing
   across northern skies between north star [11]Polaris and the Big
   Dipper. From a dark site you can only just spot it as a [12]fuzzy patch
   though. That's still an impressive achievement if you consider you are
   gazing at a visitor from the [13]distant Oort cloud with your own eyes.
   But binoculars or a small telescope will make for an even more
   enjoyable view of this [14]Comet ZTF in the coming days.
