Explanation:
Skies after the near-solstice sunset on June 17
are reflected in this calm lake.
The tranquil
twilight scene was captured near
Bashaw, Alberta, Canada, northern planet Earth.
Usually spotted at high latitudes in summer months,
night shining or noctilucent clouds hang just above the horizon,
transfusing light
into a darker sky.
Near the edge of space, the icy apparitions are
condensations on meteoric dust or volcanic ash still in
sunlight at extreme altitudes.
Also near the edge
of space on this short northern night,
solar activity triggered the lovely apparition of aurora borealis
or northern lights.
Solstice Today:
