We are organizing a one day Astronomy symposium in the Moonstone building on 22 October 2024. The scientific symposium is aimed at bringing the astronomers at the Department of Astrophysics at the University of Vienna and at ISTA together. We will create a scientific program that spans all astronomy topics that are being researched at ISTA and in Vienna (covering research on stars, galaxies, black holes, (exo)planets, instrumentation, and the Universe as a whole). In addition to talks, we plan for interactive sessions. The program will start at 9:00 and end with drinks at 17:00. The maximum number of participants is 40.
