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 lectures: Babelsberg Starry Night on 21.11.2024

For the next Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) we offer two lectures: ‘How galaxies challenge the dark matter model’ (German) by Marcel Pawlowski and ‘Intermediate mass black holes - the missing piece’ by Nikolay Kacharov. They will be broadcast on the YouTube channels ‘Urknall, Weltall und das Leben’ (Big Bang, Universe and Life) and ‘videowissen’ from Thursday 21 November 2024.

Public observation evenings in the Great Refractor in Potsdam starting at 15.11.

Over the winter months, the historic telescope now opens its dome again for public observation evenings. On six dates between November 2024 and April 2025 anyone who is interested will have the opportunity to take a look through the world's fourth-largest refracting telescope.

Research Area I: Cosmic Magnetic Fields

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.

The German MHD Days were initiated in Potsdam in 1997 as a forum for theoretical research problems in magnetohydrodynamics, predominantly in astrophysics and geophysics. Since many of the problems are of fundamental nature, links to liquid metal phenomena, turbulence, convection and rotation of fluids have been in the scope of the meeting since.
