Movie showing the evolution of gas (coloured by temperature) associated with a galaxy in the EAGLE cosmological simulation

The evolution of gas density during the formation of a galaxy similar to the Milky Way. Luminosity corresponds to gas density, the colour encodes the temperature.
Volume rendered with Typhoon by Rob Crain and Jim Geach, from a cosmological hydrodynamical simulation by Rob Crain and the EAGLE simulation (astro.ljmu.ac.uk/~astrcrai/eagle) collaboration.
