Our Mark IX Star Projector was installed in 2001 as part of a major renovation to the James S. McDonnell Planetarium. The Mark IX projects over 9,100 individual stars, in addition to the members of our solar system, the Milky Way, and a variety of deep sky objects.

Twenty years ago today, the McDonnell Planetarium’s Zeiss Universarium Mark IX Star Projector shined its first stars for the public. One of only three of its kind in the United States, this marvel has dazzled millions of stargazers with its breathtaking recreation of a clear, dark night sky. Experience it for yourself in one of our live Star Shows!  Information about our shows is available here.
