Now Showing in the Leonard Nimoy Event Horizon

The Once and Future Griffith Observatory (Daily)

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.

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 .
