Our planetarium has been a fixture of the West Hartford community for over 40 years. The Travelers Science Dome at the Gengras Planetarium is Connecticut’s largest public digital planetarium. Immersive, full dome, CGI planetarium shows provide the audience with a “you are there” experience unlike any other. Fly to Mars, experience a supernova, or travel to another solar system. The Travelers Science Dome at the Gengras Planetarium is the destination for unique, out-of-this world education in Connecticut.
