AIP

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.

Virtual lecture: Babelsberg Starry Night on 18th September 2025

At the next virtual Babelsberg Starry Night of the Leibniz Institute for Astrophysics Potsdam (AIP), Dr Marcel Pawlowski answers questions about his lectures on satellite galaxies and MOND – alternative theories of gravity. The video will be broadcast on the YouTube channel ‘Urknall, Weltall und das Leben’ (Big Bang, Universe and Life) from 18 September 2025.

Bessel Award for Dr. Alexis Rouillard

The Alexander von Humboldt Foundation has awarded the prestigious Friedrich Wilhelm Bessel Research Award to Dr. Alexis Rouillard, researcher at the Astrophysics and Planetology Research Institute in Toulouse to deepen his research on solar winds at AIP.

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.

Have you heard?

The Leibniz Institute for Astrophysics Potsdam (AIP) has suspended communication on its X account (formerly Twitter). The decision reflects concerns about the current direction of the platform, which is seen as inconsistent with our values like openness, scientific integrity, transparency and democratic discourse. AIP will continue to share news via its website and other social media platforms, such as Mastodon and Bluesky.
