US EditionOur Sun may have escaped the Milky Way’s center with thousands of twin stars
Researchers identified 6,594 solar twins whose ages cluster 4–6 billion years ago, indicating a mass migration from the Milky Way's inner region that shaped the Sun’s current orbit.

Our Sun may have escaped the Milky Way’s center with thousands of twin stars
Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of Sun-like stars billions of years ago. The journey may have carried the solar system away from the galaxy’s crowded center into a calmer region where life could eventually emerge.
Like archaeologists studying objects from the past to reconstruct the history of humans, there is a scientific branch, called galactic archaeology, dedicated to...
What caused the Sun to migrate outward?
Evidence points to an early, large‑scale stellar migration Astronomers analysing vast stellar catalogs have found a population of Sun‑like stars that share chemical signatures and orbital properties consistent with an origin near the Milky Way’s crowded central regions. The data suggest the Sun…
Gaia's telescope has discovered thousands of solar twins that can explain why a planet with conditions favourable to life has appeared near our star. And this involves large-scale star migration, reports Live Science. THE SAINTERES the Milky Way has a secret: that scientists have found in the heart of the Gaia galaxy, a European Space Agency observatory that monitored the movement of millions of stars from 2014 to 2025 in high resolution. The te…
The Sun could be one of thousands of solar twins moving through the Milky Way
For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or “wave,” of stars drifting out from the inner parts of the Milky Way. This ancient migration is what astronomers believe enabled the Sun to travel to the outer regions of the Galaxy. Although, the Sun was confined to the more densely populated areas near the center due to gravitational interactions with other stars. Assistant…
