Their expert astronomers use giant telescopes to reveal planets, constellations, nebulae, and galaxies—giving guests a chance to explore the cosmos in a fun, interactive setting.

Each tour lasts approximately two hours, starting around sunset, and includes a lively astronomy talk, hands-on telescope use, and plenty of time for questions about the universe.
