The discovery that we live in an ordinary galaxy, one of several hundred billion in the observable Universe, instigated a profound change in thinking about our place in the Universe. 

This first lecture covers the Great Debate of the early twentieth century as new telescopes and new ways of observing the cosmos put our Milky Way in its place; and looks at how subsequent observations helped us understand how galaxies like our own formed and evolved.

A lecture by Professor Chris Lintott recorded on 13 September 2023 at Barnard's Inn Hall, London
