Unlock the secrets of space through Chile's epic mountain observatories in the California Academy of Sciences' newest planetarium show, Big Astronomy. Meet the fascinating people who push the limits of technology with world-class telescopes that explore our Universe, near and far.
Due to limited seating, planetarium showpasses are handed out on a first-come, first-served basis. Please visit the cart near the planetarium entrance to pick up your tickets. Our schedule is subject to change, so it's a great idea to confirm your preferred showtime on the day of your visit.
Please note: Planetarium shows may not be appropriate for children under seven, and we regret that we cannot permit any child under 4.
