May 24 (UPI) -- Researchers in Germany have run some of the largest-ever galaxy simulations using models they hope will reveal new details about the Milky Way's formation and evolution.
Scientists used several super-computers to run the high-resolution simulations over the course of a few months. The simulations were powered by the most comprehensive physics models yet coded, and incorporated the full scope of cosmic phenomena, including gravity, star formation, gas hydrodynamics and supernova explosions.
