Night Skies

Photographer: Rob Greebon

Stepping outside on a cold, clear Hill Country night to gaze at the stars helps us escape the fast pace of our daily lives for a few precious minutes. However, growing urban sprawl and development can bring more than just air pollution — they bring “light pollution,” where unnecessary artificial light floods peaceful natural skies, making stargazing a thing of memory.

Restoring the stars’ brilliance against an unpolluted sky can be accomplished through properly designed and installed outdoor lighting. Simple downlighting and shielding techniques can reduce glare, light trespass (light shining on other properties) and sky glow (hazy, amber or pink sky on cloudy nights) while improving safety, security and the enjoyment of property.

Some urban areas in the Hill Country area have instituted outdoor lighting ordinances in an attempt to minimize light pollution, including the City of Austin, the City of San Antonio, Bexar County (near Camp Bullis, Blanco, Village of Wimberley, Helotes, Bulverde, Boerne and City of Dripping Springs. However, Texas counties do not generally have the authority to pass ordinances for effective lighting for clearer night skies. See our County Authority page here for more information about county authority in the Hill Country.

Seeing Stars in Dripping Springs

As Texas booms, the state is less and less able to brag that the stars at night are big and bright deep in the heart of Texas. In the big cities and the sprawling suburbs, and even in Far West Texas near the McDonald Observatory, light pollution is increasingly limiting our ability to enjoy the night sky. But the Hill Country town of Dripping Springs is showing that the starry skies can be preserved or restored even as the state grows. Associate Editor Forrest Wilder writes about the growing dark skies movement and how unlike many environmental woes—climate change, for instance, or the extinction of species—light pollution is eminently reversible. More from the Texas Observer.
