Sun’s Galactic Escape Tracked by Gaia’s Twin Stars
TL;DR
A Gaia-based study of ~2 billion stars found 6,594 solar twins clustered in the 4–6 billion-year range near the Sun’s current orbit, suggesting a mass outward migration from the galactic core during the Milky Way’s bar formation. The temporary lowering of a corotation barrier likely allowed Sun-like stars to drift outward, placing our Sun in a calmer region conducive to life.
