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 cosmic magnetic fields, extragalactic astrophysics and the development of research technologies in the fields of spectroscopy, robotic telescopes and E-science.

Art meets astrophysics: Mikromegas 2 exhibition in the Great Refractor

From 3 October 2022, minimal art will be on display in the Great Refractor on Telegrafenberg. The exhibition with works by the sculptor Gaedicke and graphic artist Ranft takes place in memory of a similar exhibition 40 years ago.

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.

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.

Betelgeuse recovers – for now

New observations of the red supergiant suggest that the 2019 mass ejection of its atmosphere might significantly affects its fate. This doesn't mean Betelgeuse is going to explode any time soon, but the late-life convulsions yield clues as to how red stars lose mass late in their lives as their nuclear fusion furnaces burn out, before exploding as supernovae.
