Planetarium · University of Strasbourg

This guide to the planetarium at the University of Strasbourg starts with an odd point of pride: an analog Spitz 512 star projector that astronomer Agnes Acker and observatory director Pierre Lacroute installed in 1982 kept running for over three decades. You'll hear how it worked, flinging pinpoints of light onto the dome with nothing but bulbs, lenses and gears, until it was finally retired in 2014 for a sleek digital replacement. The guide then moves to 2023, when the university opened this cone-shaped building wrapped in scorched dark timber, home to a new fifteen-meter dome with over a hundred seats for full-sky shows.
