Explanation:
Why does Saturn appear so big?
It doesn't -- what is pictured are foreground clouds on
Earth
crossing in front of the
Moon.
The Moon shows a slight crescent phase with most of its surface visible by reflected
Earthlight, known as Da Vinci glow.
The Sun
directly illuminates the brightly lit
lunar crescent from the bottom,
which means that the Sun must be below the
horizon and so the image was taken before sunrise.
This
double take-inducing picture
was captured on 2019 December 24,
two days before the Moon slid in front of the
Sun to create a
solar eclipse.
In the foreground, lights from small
Guatemalan
towns are visible behind the huge
volcano Pacaya.
