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.

Einstein Tower and Great Refractor welcome to „Tag des offenen Denkmals“

The Leibniz Institute for Astrophysics Potsdam (AIP) is inviting visitors to the Telegrafenberg in Potsdam on September 8, 2024 to take part in the „Tag des offenen Denkmals“. The focus will be on the Einstein Tower, which is celebrating its 100th anniversary this year. The Great Refractor, which has been in use for 125 years, will also open its doors to visitors on this day.

Discovery of ancient stars on the stellar thin disk of the Milky Way

Machine learning shed new light on the formation history of our Milky Way: a surprising discovery about the evolution of our galaxy using data from the Gaia mission found a large number of ancient stars on orbits similar to that of our Sun. They formed the Milky Way’s thin disc already less than 1 billion years after the Big Bang, several billion years earlier than previously believed.

Virtual lecture from the Babelsberg Starry Nights on 18th July 2024

How many brown dwarfs are there in the solar neighbourhood? Are they all known yet? The next talk of the Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) on the topic “News from the solar neighbourhood" (German) by Dr. Ralf-Dieter Scholz will be broadcast on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life) from Thursday, 18. July 2024.

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.

Discovery of ancient stars on the stellar thin disk of the Milky Way
July 31, 2024

With the help of machine learning, a team at the AIP has made a surprising discovery. Based on data from the Gaia mission, a large number of ancient stars with similar orbits to our sun have been discovered. They formed the thin disk of the Milky Way several billion years earlier than previously thought. These results provide new insights into early star formation and the evolution of galaxies.
