Scientists simulate the Milky Way galaxy with 100 billion stars

Scientists have simulated the Milky Way galaxy with its 100 billion stars, creating the most detailed model to date. This new method allows astrophysicists to track stellar evolution across vast scales, overcoming previous limitations in simulating both slow and energetic events simultaneously. The research, led by Keiya Hirashima, offers unprecedented accuracy and opens new possibilities for understanding galactic dynamics.
