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.
