Shown is a projection of the baryonic density field, where image brightness indicates the projected mass density and color hue visualizes the mean projected gas temperature. The displayed region extends by about 1.2 billion lightyears from left to right. The underlying calculation TNG300 shown here is the presently largest magneto-hydrodynamic simulation of galaxy formation, containing more than 30 billion resolution elements.
