Comet ZTF over Mount Etna Image Credit & [3]Copyright: [4]Dario Giannobile 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.
