Short Description:

The working group “100 Years Planetarium” plans actions and offers for the upcoming 100th anniversary of the construction and opening of the first projection planetarium. A star projector was first demonstrated in the fall of 1923; the world’s first planetarium opened in Munich in May 1925.

The International Planetarium Society (IPS) is preparing a worldwide celebration year to mark the 100th anniversary of these events. The role of the GDP working group on this topic is to help develop the plans of the IPS, to implement them in the German-speaking countries, and to prepare our own regional activities for this period, to inform the public about them, and to use this occasion to present to the public what modern planetariums can do today.


The members of the working group usually meet twice a year – in late April or early May (during the GDP meeting) and in November. In addition, there are meetings in the online forum of the GDP, as well as via Skype or similar.
