Fri-Sun, July 14-16  – All day

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 2023 Badlands Astronomy Festival, July 14th-16th.
