DESCRIPTION:he OUTLIERS project aims to find and study the most ancient st
 ars in our Galaxy — stars that formed shortly after the Big Bang. These 
 stars carry unique chemical fingerprints that tell us about the very first
  generations of stars\, the first supernovae\, and the early stages of gal
 axy formation. Although extremely rare and faint\, they can still be found
  today thanks to the combined power of Gaia — which maps the positions a
 nd motions of over a billion stars — and new large spectroscopic surveys
  like DESI\, WEAVE\, and 4MOST. OUTLIERS uses this data to select and foll
 ow up the most promising candidates. By studying these stellar fossils in 
 detail\, we hope to answer long-standing questions about how the first sta
 rs formed\, what elements they created\, and how the Universe evolved in i
 ts earliest phases.
