After the Summer Solstice, waiting for us just around the next bend in time’s progress, the shadow will begin its drift back toward me, slowly demonstrating the diminishing light and the shortening days.
For me, the astronomy forum centered around two days of riveting lectures that included 'Einstein was Right! Completing the 1919 Relativity Experiment at the 2017 Solar Eclipse,' 'The History of the Universe from the beginning to the end: Where did we come from, where can we go?' and 'Preventing an Asteroid Extinction.'
The easiest way to prevent light trespass beyond our homes, aside from turning off unnecessary lighting, is to minimize the unintended projection and scattering of light from poorly aimed and poorly designed fixtures.
Like preserving natural landscapes for biodiversity, preserving access to clear skies that allow human contact with the cosmos is crucial to quality of life.
