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.

Northern Lights above Potsdam and the AIP

During the night from 19th to 20th January, colleagues at the AIP managed to capture images of the Northern Lights over Potsdam and even the AIP itself. The celestial phenomenon was triggered by a solar flare that occurred at around 6 p.m. on 18 January 2026. The solar wind released by the flare reached Earth during the night, creating colourful veils in the sky.

Virtual Babelsberg Starry Night at 15th January 2026

The next talk of the Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) entitled "The interactions between stars and planets" (in German) by Dr. Nikoleta Ilić Petković will be broadcast on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life) from Thursday, 15.01.2026.

Research Group on Cosmic Jets Gets Extended

The research group "Relativistic Jets in Active Galaxies", in which the Leibniz Institute for Astrophysics Potsdam is also involved, has been investigating the powerful plasma beams emanating from supermassive black holes since 2021. Now the DFG has extended its funding.

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.

During the night of 19th/20th January, colleagues at the AIP managed to capture images of the Northern Lights above Potsdam, its surrounding area and even above the AIP campus. The celestial phenomenon was triggered by a solar flare that occurred at around 6 p.m. on 18 January 2026. The solar wind released by the flare reached Earth during the night, creating colourful veils in the sky.

The next talk of the Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) entitled "The interactions between stars and planets" (in German) by Dr. Nikoleta Ilić Petković will be broadcast on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life) from Thursday, 15.01.2026.

The next lecture of the Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) entitled “What’s wrong with the Hubble constant” (in German) by Prof. Dr. Matthias Steinmetz, will focus on determining this constant and the expansion of the Universe.

The XMM-Newton Survey Science Centre (XMM-SSC) is an international consortium across several countries and was selected by ESA to facilitate exploiting XMM-Newton's survey capacities. The XMM-SSC and ESA teams develop the science analysis software suite and the serendipitous source catalogues. In preparation of the 5th catalogue generation, the 37th consortium meeting convenes consortium members, interested scientists from the consortium institutes, and ESA scientists to discuss XMM-Newton science and developments.
