Welcome!

The Leibniz Institute for Astrophysics Potsdam (AIP) is dedicated to astrophysical questions ranging from the exploration of our Sun to the evolution of the cosmos. It focuses on the study of cosmic magnetic fields, extragalactic astrophysics and the development of research technologies in the fields of spectroscopy, robotic telescopes and E-science.

175th anniversary of the discovery of Neptune

23 September 2021 marks the 175th anniversary of the discovery of the most distant planet in the solar system. The Leibniz Institute for Astrophysics Potsdam (AIP) celebrates this event with a lecture by Professor Matthias Steinmetz on the history of the discovery in the series of virtual Babelsberg Starry Nights on YouTube.

AIP scientists receive two awards from the German Astronomical Society

The German Astronomical Society (AG), the professional society for astronomy and astrophysics in Germany, recognises scientific achievements at the Leibniz Institute for Astrophysics Potsdam (AIP) in this year's award ceremony: The Instrument Development Award goes to Professor Martin Roth, and Dr Anke Arentsen receives the Doctoral Thesis Award.

Research Area II: Extragalactic Astrophysics

Galaxies are fundamental cosmic building blocks. At the largest scales, they serve as markers to study the distribution of matter in the universe - active galaxies and quasars are particularly important because of their intrinsic brightness. Nearby objects can be spatially resolved and consist of populations with very different patterns of motion, star formation histories and chemical abundances.

Research Area I: Cosmic Magnetic Fields

Cosmic events are determined by two natural forces: gravity and magnetic fields. The magnetic field research at the AIP is mainly focused on magnetohydrodynamic (MHD) simulations, the magnetically induced activities on the Sun and the stars, solar coronaphysics as well as space weather in our solar system and on planets around other stars.
