Under One Sky 2025

November 7-8

Following the arc of night across the globe over the course of 24 hours, Under One Sky—DarkSky’s annual conference—unites a growing dark sky movement.

Join us as we share stories, explore the latest science, and unpack proven strategies through engaging virtual sessions, workshops, and keynote speakers. Whether you’re new to the mission of dark sky preservation or a lifelong Advocate, you’ll leave with new tools and connections as we work to turn the tide on the growth of light pollution to protect the night.
