The following planetariums and observatories in the Puget Sound region and around Washington State have regularly scheduled public astronomy shows that have free or cheap admission of $15 or less.
- Planetariums feature digital videos displayed on a dome-shaped screen with breathtaking images of the universe or interesting detail on related topics such as telescopes, space travel, and even earthly topics such as math and sea creatures.
- Observatories offer viewing of the night sky through telescopes (weather permitting).
Some facilities offer both digital planetarium shows as well as live telescope viewing. Unlike outdoor stargazing parties, these indoor shows are usually held rain or shine and feature a variety of topics related to astronomy (such as stars, sun, moon, planets, space, galaxies, comets, gas, and cosmic dust) and atmospheric science (including weather forecasting, climate, meteorology).
