Turbulence in the ISM (IMAGE) Gauss Centre for Supercomputing Caption Turbulence shaping the interstellar medium. The image shows a slice through turbulent gas in the world's highest-resolution simulation of turbulence, published in Nature Astronomy. Turbulence produces strong density contrasts, so-called shocks (see zoom-in). The interaction of these shocks is believed to play a key role in the formation of stars. Credit Federrath et al.
