Our sun and a host of sun-like "solar twins" may have migrated away from the core of the Milky Way galaxy together, potentially making the solar system more hospitable to life as we know it, new research finds.
Around the Milky Way are solar twins, stars that physically appear very similar to the sun.
In two new studies, researchers examined data from the European Space Agency's Gaia satellite, which captured data about two billion stars to create the most precise 3D map of the Milky Way ever made. They focused on 6,594 solar twins within about 1,000 light-years of Earth. This collection of solar twins is about 30 times larger than previous surveys of these stars.
