Sit back and experience the wonders of the night sky with expert astronomers and educators. Be prepared to open your eyes to a whole new world—or worlds!
The Seymour Planetarium is home to historically significant astronomy education tools as well as modern digital presentations. The Korkosz projector is a remarkable example of Springfield ingenuity. Still used in our planetarium presentation, this Springfield-made “star ball” is the oldest operating American-made projector in the world. A new full-dome video system using Zeiss Velvet projectors covers the dome with images and video, creating immersive experiences in Astronomy and Earth Science. These projectors are the only projectors in the world that have a pure black background, enhancing the beauty of our historic Korkosz projector’s optical star field.

Big Bird, Elmo and their friend from China, Hu HuZhu, take viewers on a journey of discovery! One World, One Sky is a brilliant spectacle of light and color as the furry friends watch the stars twinkle over Sesame Street. Children attending the show can interact as they watch, drawing constellations and counting the time it takes the sun to set. The show aims to nurture a child’s natural sense of wonder about the night sky while forging cross-cultural connections, and bridging kids across nations through a common bond in learning about the sky together. Running time: 45 minutes with live Q&A.

Did a space rock six miles wide slam into the Earth 66 million years ago and wipe out 75 percent of all living species at that time, including the dinosaurs?
