The Annual Badlands Astronomy Festival brings together space science professionals, amateur astronomers, educators, youth groups, and park visitors for a stellar experience. Celebrate the beauty of a dark night sky and the wonder of space exploration. 

Novices and experts alike will enjoy daily family-friendly activities and evening presentations with special guest speakers. In the past, activities have included planetarium visits, solar telescope viewings, technology demonstrations, and more. Nightly telescope viewings will be sponsored by the NPS Night Sky Program and Celestron.

This three-day celebration at Badlands National Park will support the continued protection and enjoyment of our incredible night skies as a precious natural resource. Although light pollution threatens dark skies across the globe, the Badlands are nestled in a corner of the Great Plains where light pollution is not a prevalent issue. Come celebrate the dark skies of the park with us!

The festival schedule and activities vary year-to-year. Stop by the Ben Reifel Visitor Center to pick up this year’s schedule when you visit or check out the schedule below. Most events and activities are located in wheelchair-accessible areas. Astronomy Festival events do not require advance registration or tickets. 

 Badlands National Park has partnered with the NASA South Dakota Space Grant Consortium to co-sponsor the 2025 Badlands Astronomy Festival, July 18th-20th.

The festival brings together space science professionals, amateur astronomers, educators, and visitors for a three-day celebration.

Novices and experts alike will enjoy the spectacular dark night skies of Badlands National Park at public star parties each evening. During the afternoon each day, a variety of family-friendly activities will provide opportunities for visitors to learn about the night sky, the sun, and space exploration. Telescopes will be provided by astronomers from the Black Hills Astronomical Society, Badlands National Park, Dark Ranger Telescope Tours and the University of Utah for day and night observations. 

The schedule of events includes a scale model solar system tour and walk, solar observing opportunities, special guest speakers, public stargazing activities, static displays, as well as equipment demonstrations by professional and amateur astronomers. 

This free event is made possible through funding and support from the Badlands Natural History Association, NASA South Dakota Space Grant Consortium, Dark Ranger Telescope Tours, Black Hills Astronomical Society, The Journey Museum and Learning Center, International Dark Sky Association, University of Utah, Badlands National Park Conservancy, Minuteman Missile National Historic Site, and Badlands National Park.
