- Programs begin promptly. We suggest you arrive an hour before showtime. Always leave yourself enough time to park the car, purchase tickets, check your coats and strollers, visit the restrooms, etc.
- Planetariums are not like movie theaters. Planetariums are too dark to allow audience members to come and go as they please (it is dangerous and disruptive). Latecomers will not be admitted.
- Visit the restrooms before the program begins. Once the lights go down, visitors can leave, but are not permitted to reenter (see above).
- Planetariums are great places for kids, but to recreate a nighttime environment the planetarium theater has to be dark. Note that strollers are not permitted.
- Please turn off cell phones, beepers and other noisy electronic or light emitting devices while inside the theater.
- Note: food and drink are not permitted in the planetarium.
Observatory
| Friday 8:30 - 10pm | Open telescope viewing (free with museum admission) |
