Next GMARS Star Party

December 16th – 18th

Join us for our final star party of 2022! Get together with your astro-family one last time this year at GMARS. Don't forget to bring a side dish, beverages, and/or a dessert for the Saturday Starbecue Potluck!

🌵 🌞 🌚 ⭐ 🔭

Come out to enjoy telescopic views of nebulae, star clusters, galaxies, planets, and more! The Moon will be new (-ish), which means the skies will be dark. Don't forget to come prepared for chilly temperatures! GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning.
