Overview
- Credit value: 15 credits at Level 5

Module description
This course is designed to provide a basic introduction to the exciting new field of astrobiology - the study of the astronomical and planetary context within which life on Earth has evolved, and the implications for the prevalence of life elsewhere in the Universe.
It will:
- introduce you to the astronomical background of the origin of life, including the origin of the necessary chemical elements and the origin and evolution of the Solar System
- introduce the concept of pre-biological chemical evolution, and familiarise you with the key theories and experimental results in this area
- provide you with an overview of the history of life on Earth and its relevance for life elsewhere, with special reference to extremophilic life
- outline the prospects for life elsewhere in the Universe, both in our own Solar System and on the newly discovered planets around other stars
- introduce you to the scientific and philosophical issues concerning the possibility of extraterrestrial intelligence.
