Galactic Turmoil

High star formation rates as the origin of turbulence in early and modern disk galaxies

Supercomputer simulation of the formation of a disc galaxy similar to our own Milky Way. The calculation follows the dynamics of gas, stars and the cosmic dark matter from the Big Bang to the present day, and enables astronomers to visualise the turbulent nature of gas dynamics in both the ancient and present day Universe.
