Scenic City Dark Sky Project “Lights Out Chattanooga” Event

Scenic City Dark Sky Project “Lights Out Chattanooga” Event - Friday 11/6/26 (5-10 PM) at Greenway Farm Park

Light pollution is increasing almost exponentially around the world. Although Chattanooga has made positive changes over the past several decades, our National Park City remains significantly impacted by the harmful effects of over-lighting. Eighty percent of the world’s population lives under sky glow, including Chattanooga and surrounding cities, which not only reduces our own connection with nature, but it drastically affects wildlife and other living things. In addition, changing our approach to the way we use outdoor lighting can be safer while also providing cost savings.

The “Lights Out Chattanooga” event is presented by the Scenic City Dark Sky Project, which is an initial collaboration between the Barnard Astronomical Society (BAS), UTC Clarence T. Jones Observatory (CTJO), and Outdoor Chattanooga to promote darker skies within the Chattanooga community. This Chattanooga National Park City Seed event is a public gathering to provide Chattanoogans with an opportunity to experience the benefit of less light pollution within the city limits. Situated on 180-acres along the North Chickamauga Creek in Hixson, Greenway Farm is an immersion into nature. Which makes this park an excellent choice to hold an inaugural event highlighting the negative effect of over-lighting.

As visitors arrive, they will first be provided with the opportunity to learn about how lighting affects everything from bird migration, insects, wildlife, and of course humans. Along with the BAS and CTJO, community partners such as the Chattanooga Audubon Society, naturalists with the City of Chattanooga, and the Chattanooga Ornithological Society will have hands-on demonstrations, fun activities, and information about the importance of everyday citizens taking small, positive actions towards darker skies by using responsible lighting.

Once the sun sets at 5:42 PM, new visitors will arrive at Greenway Farm without its traditional lighting. Instead, guests will be greeted by lots of red lights, which will allow visitors to safely navigate the park without losing their “night vision”. Small hand-held red lights will also be provided to each visitor as they enter the park.

Twilight ends and official nighttime begins at 7:09 PM that evening, so all remaining non-red lights within the park and information/activities area will be turned off. Participating residents and businesses within the surrounding area will also turn off all unnecessary exterior lighting so the public can witness the impact of those darker skies that further connect us with nature.

At this point in the evening, the event will transition into a star party! Volunteers with the BAS and CTJO will have a variety of different types of telescopes set up for the public to view celestial objects in the night sky under relatively darker conditions.

 The Scenic City Dark Sky Project is dedicated to reclaiming the natural heritage of our night sky. We advocate for reducing light pollution through safe, responsible outdoor lighting to protect our local ecosystem, enhance our community’s well-being, and ensure that the wonders and curiosities of the universe remain visible to every dreamer within the Scenic City.
