Snow King Observatory and Planetarium

Our Vision: A Unique Public Observatory & Planetarium in Jackson Hole

Wyoming Stargazing is well on its way to bringing our vision to fruition. Wyoming Stargazing has a shared vision with Snow King Mountain Resort to establish an observatory and planetarium on the summit of the mountain. The Observatory and Planetarium, designed by Jakub Galczynski and Esteam Architecture, are part of a larger Snow King Phase 2 Master Plan, which The Town of Jackson recently approved. The United States Forest Service (USFS) announced their preferred alternative based on their Environmental Impact Assessment in October of 2020 and is expected to issue a final ruling in January of 2021.


The Observatory is planned to be built on the summit of Snow King Mountain in the summer of 2021. The Observatory will have a 20′ AstroHaven dome and a 1.0-meter PlaneWave telescope. This will be one of the largest state-of-the-art telescopes in the world dedicated primarily to public outreach. Wyoming Stargazing will use this facility to reach our goal of impacting 1 million students through in-person and virtual programming by the year 2030.

The Planetarium is planned to be built in the summer of 2023. It will have a 10-meter dome with roughly 55 seats and a state of the art digital projection system from one of the leaders in planetarium design.
