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 17th September 2026

A new lecture from the virtual Babelsberg Starry Nights series will be published on YouTube, with Prof. Dr. Martin Roth: "From Carbon to Silicon" (in German). The video will be available from 17th September, 8 pm, on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life).

Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields

An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This gives clues to understanding why massive stellar eruptions are rarely observed on stars other than the Sun.

Open Day at the Telegrafenberg on 26th September 2026

On Saturday the 26th of September 2026, the Telegrafenberg will welcome visitors for an open day from 12 pm to 5 pm. The Alfred Wegener Institute (AWI), Potsdam Institute for Climate Impact Research (PIK), GFZ Helmholtz Centre for Geosciences and the Leibniz Institute for Astrophysics Potsdam (AIP) invite the public to get a close-up look at the ‘Albert Einstein’ Science Park and the top-level research carried out there.

Galactic Hearts: How Central Galactic Structures Grow Together

Using a state-of-the-art galaxy simulation, a team led by scientists from the Leibniz Institute for Astrophysics Potsdam (AIP) gained new insights into the processes shaping galactic centres across the Universe and the formation history of the Milky Way, bridging theory and observations.

The X-ray sky comes into focus – eROSITA-DE releases its second collection of public source catalogues

The German eROSITA Consortium (eROSITA-DE), with the participation of the Leibniz Institute for Astrophysics Potsdam (AIP), has released its second major public dataset, eROSITA Data Release 2 (DR2). Built from the first three all-sky scans of the eROSITA telescope aboard the Spectrum-Roentgen-Gamma (SRG) mission, DR2 provides the most sensitive and comprehensive catalogue of the X-ray sky currently available to the public.

On Thursday, a new lecture from the virtual Babelsberg Starry Nights series will be published on YouTube, with Prof. Dr. Martin Roth: "From carbon to silicon" (in German). The video will be available from 17th September, 8 pm, on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life).

The AIP is taking part in the Leibniz Association’s “Book a Scientist” event again. This offers people the chance to speak to an expert for 25 minutes and ask questions about their favourite topic. Dr Jean-Michel Désert from the AIP will be discussing the fascinating topic ‘Exoplanets: The New Worlds and the Quest for Life Therein’.
