The cornerstone for the renewed interest in astronomy in Germany was laid in the early 1960s. One of the factors behind this change was the establishment of the European Southern Observatory (ESO) in the Atacama Desert in Chile. The site – once a distant dream for Europe's leading astronomers – is now one of the most successful research institutions in the world. Several Max Planck Institutes focusing on astronomy were set up at the same time. The Centre for Astronomy Education and Outreach in Heidelberg is considered the German hub for the work of the ESO. In October 2012, together with the employees of the Max Planck Institute for Astronomy, the centre celebrated the 50th anniversary of the charter being signed. The Centre for Astronomy Education and Outreach is unique. The research institute was initiated at the end of 2008 by the Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V. and the Klaus Tschira Stiftung gGmbH foundation. The latter is a foundation which acted as the builder of the galaxy-shaped building, and the former runs the centre. The University of Heidelberg and city of Heidelberg are also partners. At the end of 2011, the Centre for Astronomy Education and Outreach moved into its own building on the Königstuhl near Heidelberg.
