Explanation:
Comet-like
plumes
are blowing over the volcanic peaks of
Mount
Etna
in this wintry mountain-and-skyscape from planet Earth.
The stacked and blended combination of
individual
exposures recorded during the cold night of
January 23,
also capture naked-eye Comet ZTF just above Etna's snowy slopes.
Of course increasing
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
Polaris and the Big Dipper.
From a dark site you can only just spot it as a
fuzzy patch though.
That's still an impressive achievement if you consider you are gazing
at a visitor from the
distant
Oort cloud
with your own eyes.
But binoculars or a small telescope will make for an even more
enjoyable view of this
Comet
ZTF in the coming days.
