Sun and Thousands of Stellar Twins Migrated 10,000 Light‑Years Across the Milky Way
New analysis of 6,594 solar‑twin stars shows the Sun traveled outward from the crowded galactic core to its current suburban orbit, moving roughly 10,000 ly. Chemical signatures and Gaia‑derived motions indicate a coordinated migration, with simulations pointing to the galactic bar’s influence.

Older Humpbacks Prove Better at Wooing Mates
Researchers studying humpback whales in New Caledonia found older males outperform younger ones in securing mates. Genetic sampling revealed that age correlates with song mastery, and females preferentially select seasoned singers. The study, published in *Current Biology*, underscores how decades of population recovery have allowed behavioral nuances to re‑emerge. It highlights that the species’ rebound provides unprecedented opportunities to observe natural mating dynamics.
