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.

A new ultra-faint dwarf galaxy has been discorved in the vicinity of Andromeda (M31), the Milky Way’s large neighbouring galaxy. The study suggests that the galaxy named And XXXVI is one of the faintest satellite galaxies discovered around Andromeda to date.

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.

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.
