“Galaxies – One Gigayear at a time”, Dr Julian Onions, public Zoom lecture, 6 Dec 2021

Cork Astronomy Club welcomed Dr Julian Onions of Nottingham University’s outreach team.   He desribed his talk thus: “What are galaxies, how are they classified, how are they formed, what do we understand about their lives, and how many pretty pictures can I fit in one talk?”         

Dr Julian Onions

If a marble at Nottingham in central England represented the Sun, he told us, the next Galaxy would be as far away as in the Irish Sea or English Channel.  Julian traced the formation of galaxies, their morphology (shapes), their pasts and their futures.  He specialises in simulations of the universe to test our theories of how it works. Thanks Julian for a great night!
