Story summary
- Scientists at Tokyo Metropolitan University used Gaia satellite data to show the Sun migrated outward from the Milky Way's center about 4–6 billion years ago, with a group of similar stars.
- They identified 6,594 solar twins, whose ages cluster near the Sun's formation.
- This suggests a mass migration rather than a solitary journey.
- The galactic bar's formation may have eased barriers, allowing stars to reach more stable regions.
