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 stellar, solar and exoplanetary physics, extragalactic astrophysics and the development of research technologies in the fields of spectroscopy, robotic telescopes and E-science.

New research group to explore the evolution of the Magellanic Clouds

Dr. Lara Cullinane has been awarded a prestigious Leibniz Junior Research Group to investigate the evolution of the Magellanic Clouds, our nearest galactic neighbours. Her project, titled ’Chronicling the Clouds: Chemodynamics of the Most Massive Dwarf Galaxies’ will use the cutting-edge 4MOST instrument to uncover how these galaxies formed, evolved, and interacted over billions of years.

Dr Joseph Whittingham is awarded the Dissertation Prize for his research on galaxy mergers and radio relics

Dr Joseph Whittingham receives a prize from the Physikalische Gesellschaft zu Berlin e.V. (Berlin Physical Society) for his doctoral thesis, which he completed under the supervision of Prof. Dr Christoph Pfrommer at the Leibniz Institute for Astrophysics Potsdam (AIP) and the University of Potsdam.

Rare High-resolution Observations of a Flare-prolific Solar Active Region

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR solar telescope in Tenerife, researchers recorded the explosive activity of the Sun’s most energetic sunspot group of 2025, revealing twisted magnetic structures and the early stages of flare ignition with unprecedented detail.

Research Area I: Stellar, Solar and Exoplanetary Physics

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.

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.

On Thursday, 11 December 2025, the Leibniz Institute for Astrophysics Potsdam (AIP) will open its doors for a very special evening in the context of a joint event organised by the „Potsdamer Lesesalon“ and the AIP. Under the title ‘Galaxies and Cosmic Cats – A Starry Night Between Science and Fiction,’ Potsdam author Tobias Radloff and Dr Ramona Augustin from the AIP invite you to join them on an interdisciplinary expedition into space.

Dr Joseph Whittingham receives a prize from the Physikalische Gesellschaft zu Berlin e.V. (Berlin Physical Society) for his doctoral thesis, which he completed under the supervision of Prof. Dr Christoph Pfrommer at the Leibniz Institute for Astrophysics Potsdam (AIP) and the University of Potsdam.
