Habitability in the Universe (IL907)


This module will draw together concepts of habitability from across the university, starting in our own Solar System and exploring how we find and understand habitable planets in the wider galaxy using modern telescopes. We will look at life at the extremes, considering extremophiles on Earth, and what they might tell us about habitable conditions elsewhere, before approaching the sustainability and long term habitability of our own planet.

Besides this initial exploration of the realities of habitability, we will turn to our own reactions to it. Popular culture is replete with the idea of the other, within our normal environment and outside of it. A sense of precariousness underpins literature and film, such as Ridley Scott’s The Martian, and in cinema the development of special effects is closely linked to the presentation of alien life and other worlds.



The overall module will consist of weekly 2 hour sessions, usually comprising a lecture followed by a more interactive seminar and discussion. During the lecture we will introduce new concepts from differing departmental perspectives. The seminars will allow the students the opportunity to synthesise these concepts into a complete understanding of ‘Habitability in the Universe’. These seminars will consist of guided discussions and group activities, as relevant to each topic covered. Each week will be led by academics from the appropriate departments. We will cover a scientific conception of habitability, in the solar system and galaxy, as well as expanding the concept progressively to include habitability in the arts.
