Explanation:
On this November morning an old crescent Moon and morning star
rise just before the Sun in a wide panoramic
skyscape from Kenya's Amboseli National Park.
Still below the limbs of an acacia tree and the eastern horizon,
the Sun's position is easy to find though.
It's marked at the left by the subtle convergence of
light and shadow in the dawn sky.
Known as crepuscular rays, the warm-colored rays of sunlight are outlined by
shadows cast
by unseen clouds near the horizon.
Arcing above the profile of Mount Kilimanjaro, toward the right
the rays of light and shadow converge at the western horizon.
There known as anti-crepuscular rays, they indicate the point
opposite the rising sun.
The
cloud shadows
are very nearly parallel, but converge toward the distant horizons
because of perspective.
