The Milky Way stretches over 100,000 light-years across. Our solar system lies on the edge of the galaxy, giving us a limited view of our cosmic home.
Gaia has recorded billions of objects, but that represents a tiny fraction of the massive galaxy in which we reside. This final illustration shows the area mapped out by Gaia—an incredible feat, but still so limited. But Gaia will remain operational until at least 2025, hopefully providing scientists with many more valuable insights.
