Explanation:
For some,
these subtle bands of light and shadow stretched across the sky as the
Sun set on July 11.
Known as
anticrepuscular rays,
the bands are formed as a large
cloud bank near the western horizon cast
long shadows
through the atmosphere at sunset.
Due to the camera's perspective, the bands of light and shadow
seem to converge toward the eastern (opposite) horizon at a point seen
just above a 14th century
hilltop castle
near Brno, Czech Republic.
In the foreground,
denizens
of planet Earth are enjoying the region's annual
Planet Festival
in the park below the Brno Observatory and Planetarium.
And while crepuscular and anticrepuscular rays are a relatively
common atmospheric phenomenon, this festival's 10 meter diameter
inflatable spheres representing
bodies of the Solar System
are less often seen
on planet Earth.
