Monthly Meeting March – Island Universes: Discovering Galaxies Beyond the Milky Way

Continuing with this months theme of the scale of the Universe, Professor Chris Lintott presents a Greshan College video lecture.

Island Universes: Discovering Galaxies Beyond the Milky Way

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 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.

This lecture was recorded by Professor Chris Lintott on 13 September 2023 at Barnard’s Inn 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.

The meeting will be followed by supper.
