VENUE CHANGE - Conway Hall
25 Red Lion Square, London, United Kingdom
In 2006, the International Astronomical Union adopted a definition of a planet that demoted Pluto to just one of what is likely hundreds of dwarf planets in our Solar System. Exploring the remote Kuiper Belt, this lecture challenges us to think about what kinds of scientific questions are worth our attention, what it means to name something – and why Pluto is worth caring about anyway.
A lecture by Professor Chris Lintott.
