"An Astronomer’s Guide to the Periodic Table" - 2019 marks the International Year of the Periodic Table - the famous diagram used to display the chemical elements that make up our universe.  Over the past century astronomers have learned a great deal about where these elements come from – including remarkable new discoveries about the cosmic origins of precious metals like gold and silver.  What is less well known, however, is the crucial importance of many rare elements underpinning the cutting-edge technology astronomers use to study the universe.  In this talk join Professor Martin Hendry MBE as he takes a whistle-stop tour of the periodic table, and how its elements have helped us reveal the mysteries of the cosmos.
