You Won't Believe Your Eyes

Discover unseen worlds and hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible in the film Mysteries of the Unseen World, now playing in the Alden Digital Planetarium: A National Geographic Theater.

The film, narrated by Forest Whitaker, uses innovative high-speed and time-lapse photography, electron microscopy, and nanotechnology, to transport audiences to an enthralling secret world of nature, events, and breathtaking phenomena not visible to the naked eye.

Mysteries of the Unseen World is now playing daily at 3:00 p.m. Tickets can be purchased at our Tickets and Information Desk on the day of your visit.
