This text shows the distribution of material from a slice taken from one of the turbulence simulations. The colors represent density, with dark blue indicating the least dense regions and red representing the thickest areas. The black dots mark the positions of the tracer particles, which move along with the material and record the conditions they encounter. This process creates a history of how pockets of density change over time. Courtesy of NASA/E. Scannapieco et al. (2024), ASU.
