Science Dialog

Argelander Institute staff members participate in a variety of events to communicate our science and methods. In the following, we present a selection of our past and upcoming activities in chronological order.

Our public relations work is substantially supported by the projects PUNCH4NFDI and B3D. For more details or your suggestions, please contact Frank Bertoldi or David Ohse.

Upcoming Events with our participation


27. January 2024:  At the science rally around Poppelsdorf, over 300 young people were able to discover various STEM subjects and courses of study for themselves. At the astronomy station, we presented the interactive ALMA model and the decision tree "Tracking the universe". Participants were also able to carry out a speed check on the Milky Way using observation data and explore the rules of the quantum world using a card game.


06. Februar 2024: Zur 24. Schnupper-Uni hielt ein Team aus AIfA-Forschenden drei Workshops für insgesamt 42 Mädchen der Klassen 10 bis 13. Neben Informationen zu Studienverlauf und Jobaussichten, kamen wir über ein Kennlern-Bingo ins Gespräch und erprobten Grundlagen der Astronomie in interaktiven Teilen am LEGO Modell des ALMA Radioteleskops und einer Übung zur Abstandsmessung im Weltall.


27. Januar 2024:  Bei der WIssenschaftsrallye rund um Poppelsdorf konnten über 300 Jugendliche verschiedene MINT-Fächer und Studiengänge für sich entdecken. An der Astronomie-Station haben wir das interaktive ALMA-Modell und den Entscheidungsbaum "Dem Universum auf der Spur" präsentiert. Außerdem konnten die Teilnehmenden mit Beobachtungsdaten eine Geschwindigkeitskontrolle auf der Milchstraße durchführen und anhand eines Kartenspiels die Spielregeln der Quantenwelt erkunden.

Young participants and David view the astronomy questions at our station.

TAG DER NATURWISSENSCHAFTEN                           
12. January 2024
: A group of 22 pupils and one teacher from Beethoven-Gymnasium visited the AIfA. Insights into our work were offered in a program consisting of visits to the telescope, the LEGO model of the ALMA radio telescope and the electrical workshop, as well as scientific lectures and practical exercises. The various opportunities for interaction with AIfA researchers and students, who answered the students' questions about the everyday life and work of astrophysicists in a dialog session and during the joint pizza lunch, were particularly well received. The central theme was the expansion of the universe: how do we know that the universe is expanding and how do we measure distances? Using „Project Andromeda“, which was developed at the AIfA and is available online, the pupils tried their hand at being astronomers.

Nacht der Technik

20. October 2023: The Bonn/Rhine-Sieg Night of Technology entered its third edition and the University of Bonn was represented for the first time with its own station. As one of 49 locations in the region, the University of Bonn opened its doors and showcased technical innovations with interactive experiments in robotics, geodesy/geoinformation and astronomy.

25-30. September 2023Highlights der Physik in Kiel.  With a large hands-on exhibition including our LEGO-ALMA model, a varied program for children and young people and many interesting lectures, the "Highlights of Physics" showed how exciting and understandable science can be communicated. Almost 40,000 interested people visited the festival during the six days of the event.

19-20 August 2023:  We were invited to exhibit our LEGO-ALMA model at the Open Day of the Federal Ministry of Education and Research. Under the motto: New horizons, new opportunities - knowledge that moves us forward! a selection of initiatives and projects supported by the BMBF was presented here, among other things. Despite sweaty temperatures, more than 7000 visitors found their way to the Federal Ministry in Berlin. The AIfA was represented by Minou Greve, Leo Ringel and Philipp Ertz.

Roadshow "Universe on Tour"

9-13 August 2023:  As part of the "Universe on Tour" roadshow, more than 4,000 visitors came to the exhibition tent on the Hofgartenwiese in Bonn, where they also enjoyed the interactive LEGO-ALMA model. In the neighboring mobile planetarium, Prof. Andrina Nicola took the audience on a "Journey into Darkness." in a public evening lecture on Aug. 12. Our MS Science exhibit was displayed as a large banner.

Dialogue on Deck

4 August 2023:  More than 100 visitors attended the public panel discussion "Dialogue on Deck: Black Holes and the Limits of Space and Time", where experts from different disciplines discussed questions about the nature of space and time and the limits of our knowledge. The event took place on the exhibition ship MS Wissenschaft as part of the Science Year 2023 "Our Universe" and was organized by AIfA staff, enaCom and the TRAs of the University of Bonn.  (more) (video)

Exhibit on the MS-Wissenschaft

9 May to 27 September 2023: Bonn University was on board the "MS Wissenschaft". For this exhibition ship, a team from the university developed an exhibit in line with this year's theme of the Year of Science, "Our Universe". Under the motto "On the trail of the universe", visitors, especially schoolchildren, can interactively explore various research areas and methods relating to the universe.  (more)

Our exhibit directs visitors to cards with detailed information and links to a  website  for interactive engagement with 13 different research topics.

Science festival

9 July 2023: The first science festival of the University of Bonn on the Hofgartenwiese had the motto "Science to participate for everyone!" The AIfA was represented with the LEGO-ALMA model.  (more)

By playing with the LEGO model of the ALMA observatory, visitors could interactively learn how a radio astronomical interferometer functions.
