International Dark Sky Week (IDSW) was observed in Vermont from April 13–20, 2026.
Thank you to everyone who participated in events, conversations, screenings, proclamations, and public outreach during the week. The week helped highlight the growing interest across Vermont in protecting dark skies and reducing wasteful light.
Cebrated each year, IDSW is a global celebration of the night and an opportunity to learn more about light pollution, enjoy the night sky, and take practical steps to protect it. It highlights the importance of darkness for wildlife, human well-being, scientific discovery, and our shared experience of the stars.
Events
Events during the week included public talks, screenings, and community engagement activities that brought together advocates, local boards, educators, astronomers, and members of the public.
