Explanation:
Comet Lemmon putting on a show for cameras around the globe.
Passing nearest to the Earth this week, the
photogenic comet
C/2025 A6 (Lemmon) is now extending
two long tails :
a blue ion tail and a white dust tail.
The ion tail is pushed away from the Sun by the ever-present by ever-changing solar wind,
and shows structure also created by how much
gas is ejected at any one moment.
It glows because it is ionized by
high energy sunlight.
The dust tail is pushed away from the comet by
sunlight and shines by reflecting sunlight.
The
featured image is an enhanced composite of
50 exposures all taken two days ago from
Mlynica,
Slovakia.
The mountains in the foreground are the
High Tatras
that partly separate Slovakia from
Poland.
Although
Comet Lemmon is
best visible in long camera exposures, the
shedding ice ball has become faintly
visible in northern skies
even to unaided eyes through dark skies toward the west after sunset.
