Explanation:
How can the Moon rise through a mountain?
It cannot -- what was
photographed here is a
moonrise through the
shadow of a large
volcano.
The volcano is Mauna
Kea,
Hawai'i,
USA,
a frequent spot for
spectacular
photographs
since
it
is
arguably
the
premier
observing
location
on
planet
Earth.
The Sun has just set in the
opposite direction,
behind the camera.
Additionally, the
Moon has just passed full
phase -- were it precisely at
full phase it would rise, possibly
eclipsed, at the very peak of the shadow.
Refraction of moonlight through the
Earth's atmosphere makes the Moon appear slightly oval.
Cinder cones from old volcanic eruptions are visible
in the foreground.
Cloud tops below
Mauna Kea's summit
have unusually flat tops,
indicating a decrease in
air moisture that frequently keeps the air unusually dry,
another attribute of this
stellar observing site.
