On this November morning an old crescent Moon and morning star (Venus) rise just before the Sun in a serene skyscape from Amboseli National Park. Still below the limbs of an acacia tree and the Kenyan horizon, the Sun's position is easy to find, though. It's marked 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. The cloud shadows are very nearly parallel, but converge in the distance because of perspective.
