Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this weeks video we take a look at ESA's Gaia mission and its ultimate 3D map of the Milky Way galaxy! Discover how Gaia measured the precise position, parallax (distance), and proper motion for nearly 2 billion stars. Learn about incredible discoveries like the Gaia-Enceladus galaxy merger, detailed asteroid orbits, distant quasars, and massive stellar black holes hidden in our galaxy. Understand why the Gaia space telescope finished operations in March 2025 and what the future holds, including upcoming data releases (DR4, DR5) from this groundbreaking astronomy mission.
