Next GMARS Star Party

June 16th – 18th

Join us for our next star party at GMARS, our dark sky site in the Mojave Desert near Joshua Tree National Park. Be sure to check the weather and dress accordingly — Conditions can change quickly, so be prepared! Be sure to bring a side dish to share if attending the Saturday Star-B-Q!

🌵 🌞 🌚 ⭐ 🔭

Recharge under the night sky, and enjoy great telescopic views of planets, star clusters, nebulae, galaxies and more! GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning.
