The simulation and visualisation of the largest turbulence in space to date was honoured by the international journal HPCwire at “The International Conference for High Performance Computing, Networking, Storage, and Analysis” (HPC25), Nov. 16-21, 2025 in St. Louis.
This groundbreaking study has mapped the full range of turbulent energy across scales in a simulation of the Interstellar Medium with unprecedented numerical resolution. It illustrates the chaotic processes and movements of gases in which stars can form. The results challenge previous assumptions about the role of magnetic turbulence and show where research for further space experiments could begin. Ralf Klessen (ZAH/ITA), Heidelberg expert on interstellar turbulence, is one of the co-authors of the research paper.
We warmly congratulate the core team around James Beattie, Christoph Federrath, Ralf S. Klessen, Salvo Cielo and Amitava Bhattarcharjee on this success.
For further information about the simulation results see the respective ZAH Press Release.
