Colorful Fall Foliage: Astronomy Affects Nature
The
annual change in color of leaves, from the ubiquitous greens of Spring
and Summer to the yellows, golds, oranges, reds, crimsons, purples, and
browns of many deciduous trees and shrubs in the Autumn, is one of the
greatest visible effects of Astronomy on the natural world we live in.
The increasing length of darkness, each day in Autumn, is the primary
cause of this color change.
