    Deep Learning Speeds up Galactic Calculations

    Four square images showing dark backgrounds with stars and galaxies
    Divide and conquer. The upper images show a wide area of a galaxy being simulated. The time resolution is very low, in which each “step” of the simulation is around 100,000 years. The lower images show the specific area affected by a supernova explosion and have a finer time resolution where each step is under 10,000 years. These regions are combined with the more general simulation to improve the overall accuracy and efficiency of the simulation. ©2023 Hirashima et al., NASA/JPL-Caltech/ESO/R. Hunt/Hubble/L.

    A new way to simulate supernovae may help shed light on our cosmic origins. Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies...
