One World, One Sky is a 27-minute full dome planetarium show that follows Sesame Street’s Big Bird and Elmo as they explore the night sky with Hu Hu Zhu, a Muppet from Zhima Jie, the Chinese co-production of Sesame Street. Together, they take an imaginary trip from Sesame Street to the moon, where they discover how different it is from Earth. At the end of the show, Big Bird, Elmo, and Hu Hu Zhu pick a friendship star to remind them that no matter how far apart they might be, they can always look into the night sky and cherish their shared memories.

One World, One Sky is a production of Adler Planetarium, Sesame Workshop, Beijing Planetarium, and Liberty Science Center and was produced with major support from the National Science Foundation. One World, One Sky is distributed by Loch Ness Productions.

Back to the Moon for Good In case you haven’t heard, the Moon is trending again… and in a big way. Narrated by Tim Allen (voice of Buzz Lightyear), this is a complete behind-the-scenes feature on the $30 million Google Lunar XPRIZE, the largest incentivized prize in history. Adapted from the award-winning digital planetarium show, the 24-minute movie chronicles 18 teams from around the world looking to make history by landing a privately funded robotic spacecraft on the Moon. This global competition is designed to spark imagination and inspire a renewed commitment to space exploration, not by governments or countries – but by the citizens of the world.

Show time: 12 PM
