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.

Babelsberg Starry Night Live at 14th October 2025

During the winter months of 2025/26, the Leibniz Institute for Astrophysics Potsdam (AIP) is once again inviting visitors to the popular Babelsberg Starry Nights - live on site. Dr Peter Weilbacher will start the series with his lecture ‘Fire in the Nebula – A Look at the Most Luminous Star-Forming Regions in the Universe’ (in German) on Tuesday, 14 October 2025 at 7:15 p.m.

A look into the heartbeat of a star

Scientists at the AIP have uncovered the intricate magnetic heartbeat of a distant star remarkably similar to our own Sun—but much younger and more active. This groundbreaking study, part of the Far Beyond the Sun campaign, follows nearly three years of ultra precise observations and sheds new light on how stars like our Sun generate their magnetic fields—and how these fields evolve over time.

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.
