Featuring spectra from 250,000 halo stars, the dataset covers giant stars reaching 65,000 light-years away, fast-moving local stars, and ancient cosmic relics.
Over 80% of these dead stars are new to the survey, with more than 40% located in the Southern Hemisphere.
Mapping local neighbourhoods and stellar birthplacesCloser to Earth, the Solar Neighbourhood Census provides spectra for 280,000 nearby stars within 300 light-years of the Sun.
In addition, the Young Galaxy Program quadrupled in scale to cover 200,000 young stars, planet-forming nurseries, and massive OB stars that define the galaxy’s spiral arms.
Meanwhile, research utilising the new release identified the first five carbon-enhanced metal-poor stars in the Large Magellanic Cloud.
