Description

Swirls Upon Swirls These intricate swirls come from a high- resolution simulation of two fluids flowing past each other. In nature, such swirls can be seen over a wide range of phenomenon including mixing milk into coffee, the storms on Jupiter and even the flow of gas within galaxies.

ZOOMING IN This particular image is from a simulation of the Kelvin Helmholtz instability, which describes two fluids flowing past each other. Here, cold and dense gas is flowing past hot gas inside a galaxy, visualized through a code called “Athena”. I ran this simulation on a supercomputer using over a thousand processors.
