Mapping the stars is, perhaps, the oldest of astronomical pursuits, but it has been perfected by the European Space Agency's Gaia mission, which is providing an exquisitely precise map showing the positions and movements of the nearest two billion stars. Starting with a history of mapping the cosmos, this lecture describes the new and dynamic history of our Milky Way galaxy that results, and will move to explaining the dynamic and growing nature of our galaxy.

This lecture was recorded by Chris Lintott on 26th February 2025 at Conway Hall, London

Chris is Gresham Professor of Astronomy.

He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.
