340,000 stars’ DNA interrogated in search for Sun’s lost siblings | Australian Astronomical Observatory
Using the Anglo-Australian Telescope (AAT), an Australian-led group of astronomers working with European collaborators has revealed the “DNA” of more than 340,000 stars in the Milky Way, which should help them find the siblings of the Sun, now scattered across the sky. This is a major announcement from an ambitious Galactic Archaeology survey, called…
