The new 190-seat Leonard Nimoy Event Horizon presentation theater dramatically expands the Observatory's programming and education capabilities. The opening public presentation - "The Once and Future Griffith Observatory" - is a 24-minute film which weaves the history, recent renovation, and future of the Observatory into a tale of observation and inspiration. The theater also hosts live programs and demonstrations.

Seating for all events in the Leonard Nimoy Event Horizon is provided on a walk-in, first come, first served basis. To the extent possible, shows will be presented on the posted schedule. However, it is possible that technical difficulties or required maintenance will cause the cancellation of one or more shows. We regret any inconvenience this may cause.

The Once and Future Griffith Observatory provides an exciting and compelling introduction to the history and unique public offerings of the Observatory. This 24-minute film, entertainingly narrated by Leonard Nimoy, reveals how the vision of one man led to the creation of an architectural, cultural, and astronomical icon for southern California. The film offers an overview of the Observatory's programs and exhibits and discusses how the building was renewed during the 2002-2006 renovation and expansion project.
Show Times: Every hour on the hour.

Let's Make a Comet is a 25-minute demonstration program that mixes common household ingredients with dry ice to make a small comet that's just like the real thing. The program explores the nature of water in all its forms - solid, liquid, and gas - and discusses why water is so important to life on Earth. Recent images and discoveries from NASA missions reveal where we might find water - and possibly life - on other worlds in our solar system. Families with children will especially enjoy Let's Make a Comet.
