The Gaia telescope spotted more than 6,000 sunlike stars, all of which appear to have migrated from the galaxy's center more ...

Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

Our solar system is speeding through the galaxy at more than three times the velocity scientists once believed, according to a new peer-reviewed study. The findings,released in November 2025, could ...
