The Hamburg Planetarium is a famous planetarium located in the Winterhuder Water Tower in Hamburg, Germany. This planetarium was built in 1930, making it one of the oldest planetariums in the world. In the 1970s and 1980s, Dr. Erich Übelacker helped popularize this attraction by expanding its program; he was successful, and his visitor numbers increased drastically. Übelacker also led a redesign of the planetarium’s program. In 2009, the Hamburg Planetarium underwent another renovation, making it one of the most technologically advanced planetariums in the world. Today, the Hamburg Planetarium is one of the most successful planetariums in the world, with over 300,000 visitors walking through its doors every year. Visitors can view the “Sky Theater,” which uses multiple projectors to display a detailed image of a starry night sky on the 20m wide dome. Visitors can also participate in other exhibits like the Mensch Kosmos shows pictures taken by the Hubble Telescope and the Starry Sky of the month, which displays the current month’s astronomical features.
