Karlsruhe Planetarium uncovers the science behind the Star of Bethlehem this Christmas

Karlsruhe Planetarium has launched a special Christmas show that delves into the mystery of the Star of Bethlehem. The event takes place in the planetarium's new facility at Alter Schlachthof, which opened its doors in May. Visitors can now explore the night sky while learning about the possible astronomical origins of the famous biblical star.

The show invites guests to recline in circular seating beneath the planetarium's dome, where a projection of the night sky surrounds them. Managing director Björn Wirtjes leads the audience through key constellations, including Delphinus, Pegasus, and Cassiopeia. One of the highlights is the discussion of whether the Star of Bethlehem could have been a supernova.

The programme blends astronomy with the Christmas story, offering two distinct experiences. Adults and children aged nine and older can attend the main show, which examines the science behind the legendary star. Meanwhile, younger viewers—ages five and up—enjoy a separate presentation that uses the starry sky as a backdrop for the Nativity tale. The Christmas specials will run until January 6, with tickets available for purchase online. Beyond the seasonal events, the planetarium continues to expand its exhibitions, featuring displays on planets, stars, and galaxies. A model of a black hole is also under development for future visitors.

The new show at Karlsruhe Planetarium combines festive storytelling with scientific exploration. By linking ancient traditions to modern astronomy, the event offers a unique experience for families and space enthusiasts. Tickets remain on sale for performances throughout the holiday season.
