Astronomically speaking, there are a number of ways in which life on Earth could be wiped out. For example, a giant asteroid could hit Earth with such energy that the oceans are boiled off.

This lecture will assess which astronomical events are likely and which are not. [It will not consider anthropogenic means by which life on Earth might end].

A lecture by Katherine Blundell OBE recorded on 29 March 2023 at Barnard's Inn Hall, London.
