The Max Planck Institute for Radio Astronomy (German: Max-Planck-Institut für Radioastronomie) is located in Bonn, Germany. It is one of 80 institutes in the Max Planck Society (German: Max-Planck-Gesellschaft).
By combining the already existing radio astronomy faculty of the University of Bonn led by Otto Hachenberg with the new Max Planck institute the Max Planck Institute for Radio Astronomy was formed. In 1972 the 100-m radio telescope in Effelsberg was opened. The institute building was enlarged in 1983 and 2002.
The southern wing of the whole complex is occupied by the Argelander Institute of Astronomy of the University of Bonn.
The Institute has three main research groups, each with its own Director - Fundamental Physics (director Michael Kramer), VLBI (director Anton Zensus) and Millimetre Astronomy (director Karl Menten).
The International Max Planck Research School (IMPRS) for Astronomy and Astrophysics is a highly competitive-entry graduate program offering a Ph.D. The school is run in cooperation with the University of Bonn and University of Cologne.
