Comet ZTF over Yosemite Falls

They are both falling.
The water in
Yosemite Falls,
California,
USA,
is falling toward the Earth.
Comet ZTF is falling toward the
Sun.
This double cosmic cascade was captured late last month as fading
Comet C/2022 E3 (ZTF)
had just passed its closest to planet Earth.
The orange star just over the falls is
Kochab.
With the exception of a brief encounter with a
black bear, the
featured image was a
well-planned composite of a moonlit-foreground
and long-duration background exposures -
all designed to reconstruct a deep version of an actual single sight.
Although Comet ZTF is
now fading as it glides back to the outer
Solar System, its path is
determined by gravity
and so it can be considered to still be falling toward the Sun --
but backwards.
