  In this exploratory submission we present the visualization of the largest
interstellar turbulence simulations ever performed, unravelling key
astrophysical processes concerning the formation of stars and the relative role
of magnetic fields. The simulations, including pure hydrodynamical (HD) and
magneto-hydrodynamical (MHD) runs, up to a size of $10048^3$ grid elements,
were produced on the supercomputers of the Leibniz Supercomputing Centre and
visualized using the hybrid parallel (MPI+TBB) ray-tracing engine OSPRay
associated with VisIt. Besides revealing features of turbulence with an
unprecedented resolution, the visualizations brilliantly showcase the
stretching-and-folding mechanisms through which astrophysical processes such as
supernova explosions drive turbulence and amplify the magnetic field in the
interstellar gas, and how the first structures, the seeds of newborn stars are
shaped by this process.
